Good evening! It's around an hour until kickoff at Oakwell, where Everton will be looking to avoid an upset against League One side Barnsley. The team news is out so let's start with a look at the lineups.

BARNSLEY STARTING XI: Davies, Wabara, Roberts, Nyatanga, Mawson, Watkins, Scowen, Crowley, Hourihane, Pearson, Winnall

EVERTON STARTING XI: Robles, Pennington, Stones, Jagielka, Oviedo, Besic, Cleverley, McGeady, Naismith, Mirallas, Lukaku

BARNSLEY SUBSTITUTES: Townsend, Rothwell, Wilkinson, Smith, Digby, Maris, Templeton

EVERTON SUBSTITUTES: Howard, Browning, Holgate, Deulofeu, McCarthy, Barkley, Kone

Barnsley manager Lee Johnson has stuck with the same starting lineup that shared a goalless draw with Bradford City in League One at the weekend.

By contrast, Roberto Martinez has made seven changes to the side that started their defeat to Manchester City in the Premier League at the weekend. Goalkeeper Joel Robles comes in for Tim Howard, while Steven Naismith and Kevin Mirallas both come in.

Barnsley will certainly be familiar with a couple of names on the Everton teamsheet this evening. John Stones is understood to have handed in a transfer request at Everton, so could be making one of his final appearances for the Toffees against his old club. The England international moved to Goodison Park in January 2013. Mason Holgate is also among the substitutes for the visitors. He only joined Everton from Barnsley 14 days ago.

Barnsley have made a solid start to their league campaign, recovering from defeat on the opening day of the season with back-to-back wins before drawing with Bradford, leaving them 10th in the table after four fixtures.

Everton have had a mixed start to the Premier League campaign, with one win, one draw and one defeat from their first three matches. Although Martinez has made numerous changes to his starting lineup, it's still a strong squad for the trip to the third tier side. With no European football to look forward to this season, Martinez is clearly taking the domestic cups seriously.

If you were following any of last night's action from the League Cup, you probably know that the draw for the third round has already taken place. The winner of this match has a trip to the Madejski Stadium to look forward to, as they travel to Reading.

Here are the visitors arriving at Oakwell a little earlier:

It's been a while since Barnsley had a decent run in the League Cup. They haven't made it to the third round since the 2009-10 campaign, when they eventually reached the fourth round, where they were beaten by Manchester United.

This has been a difficult competition for Everton in recent years. The Toffees have never lifted the League Cup, but they've been beaten in the final twice, in 1977 and 1984. Their last run beyond round four came in 2008, when they last in the semi-finals. That was their first run past round four since 1988.

Ahead of this match, Barnsley manager Lee Johnson told reporters: "The lads are hungry and committed. The Key message is to impose yourself o the game and demand more from yourself and your teammates, but most importantly play with freedom and someone might just be a hero."

Meanwhile, Roberto Martinez said at his pre-match press conference: "We knew we had three big games in seven days and it is a really good opportunity to challenge ourselves. There is not such things as a strongest or not strongest first 11. We have a really good squad and we need to be ready."

There's probably one name on the Everton team sheet that's a little unfamiliar. That's because defender Matthew Pennington is making his competitive debut for the visitors this evening. He's come through the club's academy, and has previously had spells on loan with Tranmere Rovers and Coventry City. The 20-year-old penned a three-year contract extension over the summer.

This will be the first meeting between these two sides since 1998, when both sides played in the Premier League. In the 1997-98 season, Everton secured a home win over Barnsley, before sharing a 2-2 draw at Oakwell. However, this is the first time that they have been drawn against each other in this competition.

Both sides will be hoping that they can change their recent form in this competition tonight. Everton have lost their last five away matches in the League Cup, while Barnsley have won just one of their last nine, and have scored in just one of their last six League Cup matches at Oakwell.

One of the key players for the home side tonight will be goal-scoring midfielder Conor Hourihane. The Irishman has already opened his account this season, scoring the winner in their 1-0 victory over Burton earlier this month. He was the club's top scorer last season with 14 goals in 53 appearances in all competitions.

PREDICTION! The players should be making their way out ready for kickoff shortly, so there's just time to make a prediction. Everton obviously start as favourites, with nine full internationals in their squad this evening. Barnsley haven't been at their best in this competition in recent years, but will surely be keen to make it as difficult as possible against a couple of their old players. The Toffees should still have enough though, so I'm going for 2-1 to the visitors.

In case you missed the announcement earlier this week, all fixtures in the League Cup will have a two-minute silence prior to kickoff in memory of the victims of the Shoreham air disaster at the weekend, so the players will come together on the centre circle before the action gets underway.

The pressure is certainly on Everton to get a result tonight. There were few upsets in last night's fixtures, with Watford the only top flight side to have missed out. If you missed any of last night's results, you can catch up on the action here.

The players head out in front of a packed Oakwell, with the home crowd greeting the players enthusiastically. It's not quite a sell out, but there's clearly plenty of support, particularly for the home side.

The crowd falls silent briefly as the two sides line up on the edge of the centre circle for the two-minute silence. As with all of last night's matches, the silence is well-observed.

KICKOFF! Barnsley get the action underway!

CHANCE! Barnsley are more than happy to take the game to Everton in the opening moments of this tie as Daniel Crowley rushes forward before squaring it to Josh Scowen, but his shot from just outside the box is wide of the post.

The visitors are soon making their way back down the other end. Bryan Robles charges down the left flank before cutting inside. He has Steven Naismith as an option in the middle, but he takes the shot on himself, and it's a poor finish, failing to test Adam Davies.

Pennington comes under pressure as Everton move the ball around at the back, with Sam Winnall trying to hurry the Everton debutante, but he keeps his cool and passes back to defensive teammate John Stones, who then clear the danger.

Barnsley win a throw in level with the edge of the box, and Marley Watkins launches it in deep. Robles flaps at it, leaving it loose in the box, but the referee thinks that the keeper was impeded, so gives the visitors the free kick.

CHANCE! Everton immediately make their way back towards the other end of the pitch, resulting in Kevin Mirallas facing Adam Davies one-on-one. The Barnsley keeper makes an excellent diving save though, before pouncing on the loose ball ahead of the on-rushing Aiden McGeady.

Barnsley haven't been put off by Everton's near miss, as Crowley and Ben Pearson quickly work it back to the edge of the Everton box. Pennington wins it back for the visitors though, and he connects with Lukaku down the right flank. It's certainly been a high-pace opening 10 minutes at Oakwell, with both sides clearly well up for this tie.

Mirallas and Lukaku team up on the edge of the box, with the striker trying to square it back to the winger, but it's intercepted by Roberts. A full-blooded challenge from Besic wins it back, which irks the home crowd who think that it was a foul, but the referee is happy with it. Speaking of the crowd, the Everton fans have been making themselves heard in the opening couple of minutes on the subject of Chelsea's interest in John Stones. Let's just say they're warning Jose Mourinho off the defender, with some rather choice language.

CHANCE! Lukaku is really starting to test the Barnsley defenders as he finds himself in space on the edge of the box again, but three home players quickly surround the Belgian international as he tries to turn on goal, preventing him from getting the shot away. Oviedo picks out the striker again moments later, but Alfie Mawson is there to hook it clear.

CHANCE! A one-two between Mirallas and McGeady results in a shot for the former, but he can only drive his low strike straight at Davies, leaving the Barnsley keeper with an easy stop.

Scowen gets the better of Stones as he runs at the Everton goal before passing it out wide for Crowley. The midfielder tries to get past Pennington, but some decent pressure from the young defender forces a mistake from the Barnsley man.

CHANCE! Pennington is showing absolutely no sign of nerves as he makes a run forward, crossing it in towards Lukaku, but the striker can't quite stretch far enough to guide it in.

McGeady is away down the right this time, and delivers another cross for Lukaku. The striker's first touch is poor, and he knocks it to the edge of the box where Mirallas is waiting, but Barnsley quickly make the clearance. Everton are finding their record signing well in the box, but the Barnsley defenders are making it difficult for him.

Well, well, well, could an upset be on the cards? Everton have probably had the better of the chances so far, but it's Barnsley who take the lead as Sam Winnall is given an absolute acre of space in the box. Watkins flicks it back on for the striker, who has ages to turn on goal before rifling it past John Stones and into the bottom left corner.

PENALTY APPEAL! The visitors, and particularly the travelling support, want a spot kick as Josh Scowen barges Kevin Mirallas out of the way in the box. The Everton winger goes to ground, but the referee waves play on. Everton have a corner as a result, but the danger is easily dealt with by the home side.

What an amazing atmosphere there is in Oakwell following Winnall's goal! They're cheering again as Watkins sprints free down the wing, but the referee calls it back for an offside.

Roberto Martinez is fuming as his side let in a second in quick succession. Marc Roberts comes forward to launch a long throw into the box. It's initially cleared, but the defender gets a second chance to cross it back in, and Watkins gets his head to it, nodding it into the bottom corner for his first Barnsley goal. The visitors look absolutely shell-shocked.

Remember, Everton don't like playing away from home in this competition:

Barnsley clearly want to make the most of their opportunities while they're on top as Watkins gives everything to chase down a long ball forward, only to find that there's no-one waiting in the middle. Joel Robles is yet to make a save for Everton this evening, with the hosts scoring from both of their shots on target so far.

Everton just aren't closing their opponents down at the back at the moment, giving Crowley plenty of time to look for options as he plays the ball down the left. Pennington gets back to block his ball in towards Hourihane though.

BOOKING! The scorer of the first goal is also the first man to pick up a booking this evening as Sam Winnall puts one in late on Tom Cleverley.

CHANCE! The Barnsley defenders continue to frustrate Lukaku! Naismith has only the keeper to beat as he bursts into the box, but he takes a touch too many, allowing Davies to get back. The Scottish international pulls it back to Lukaku, but he can only thump his shot straight into Roberts, whose block is enough to clear the danger.

CHANCE! Everton are seeing the majority of the ball as they try to get themselves back into this match, but Barnsley's defending has been excellent. This time, Lukaku crosses it in, setting up McGeady, but Davies is ready to make the save.

Everton are camped on the edge of the Barnsley box, desperate to cut the deficit before the break. Cleverley plays it through to Naismith, who tries to back-heel it to Lukaku, but Roberts is in the right place at the right time to block yet again. The right-back has been brilliant so far.

Everton have a corner, which Stones goes up for, but Mawson manages to scuff it clear. Besic is waiting around 30 yards out and drills it back in, but it's deflected behind on its way through a packed penalty area.

As half time approaches, Roberts is called upon again to put the ball behind for a corner, with McGeady attempting to set up Lukaku from a cross. The initially delivery is cleared, before Oviedo tries to play it back in, but Mawson flicks it clear.

McGeady has worked tirelessly since Everton let the second in, using his pace down both flanks to try to set something up for the visitors. Once again though, Roberts spots the danger and clears before Naismith and Lukaku, who were both lurking in the box, can get anything to it.

AS a minute of stoppage time if played, Roberto Martinez rather interestingly makes his way off a few seconds early. He's clearly got plenty to say to his players at half time.

What a first half it's been. Two goals in six minutes for Barnsley have given them one foot in the third round of the League Cup at the expense of Premier League side Everton. They'll need another impressive 45 minutes to hold off a comeback from the visitors, but it's been a mightily impressive display so far.

Two players have really stood out for the hosts so far. Marley Watkins was involved in the build up to the first goal, before scoring the second, while defender Marc Roberts, who was playing in the National League with Halifax Town last season, set up the second, while making a string of crucial blocks and clearances at the back.

Looking at the stats, it's clear that Barnsley have made the most of their opportunities, while Everton have been wasteful. The visitors have had 63% possession, and 11 shots, including four on target, yet remain two goals adrift. With just seven attempts on goal, Barnsley have had just three efforts on target, although one was a long through-ball rather than a shot. The other two have both beaten Joel Robles.

Expect changes from Roberto Martinez early in the second half. He couldn't get off the pitch soon enough at the interval, and had a word with Ross Barkley immediately before heading off. Could that mean the in-form midfielder is coming on at the start of the second half?

One positive Everton can take from the first half is the performance of defender Matthew Pennington this evening, who has been making his first appearance for the club. The 20-year-old was tested early on, with the hosts possibly hoping to take advantage of some debut nerves, but the 20-year-old has looked solid at the back, and shown some skill getting forward too:

SUBS! Here come the Everton changes. Ross Barkley and Gerard Deulofeu are on for Aiden McGeady and Matthew Pennington.

RESTART! Everton get the second half underway.

It's also worth noting that the half-time interval has given the away fans a chance to get their anti-Bill Kenwright banners out. As they continue to display their protest signs, Ross Barkley tries to make an immediate impact as Lukaku pulls is back for the midfielder. His initial shot is blocked by Scowen, before he blasts the second over.

Barnsley are on the attack as well early in the second half as Sam Winnall charges down the left, getting the better of John Stones, but there's no-one else up for the home side, and the move stalls.

Crowley and Pearson patiently play the ball through the middle for the home side, which is something they haven't done a great deal of this evening, preferring to go for pace on the flanks. They set up Scowen for a long range drive, but his shot just rises a fraction too high.

The ball is crossed in from the wing towards Lukaku, but it's slightly overhit. The loose ball in the box drops kindly to Mirallas though, leaving him to smash the ball into the roof of the net from close range. Game on

Barnsley want the two-goal cushion back as Winnall plays the ball forward for Watkins, who flashes a low cross right in front of the Everton goal, but there's nbo-one there to tap in. Mirallas quickly tries to catch the home side out with a quick counter-attack back towards the Barnlsey goal, but the Tykes just manage the scramble it clear. This a finely poised cup tie, and a very entertaining one at that.

CHANCE! A lovely one-two between Lukaku and Deulofeu sets the latter up for a shot. Davies keeps it out with a save from his foot, but it's only clear as far as Barkley. The substitute rushes his finish though, slicing it well wide.

Naismith dummies his way into the Barnsley box before trying to slip it through to Barkley, but Roberts is continuing his performance from the first half, blocking and clearing for the home side.

Everton win a free kick right on the edge of the box, giving them chance to get numbers forward. Deulofeu curls it in, but Pearson is there to head it away for the League One side.

What a turnaround it's been by Everton! Deulofeu makes a move down the right, getting the better of Nyatanga and Hourihane to cross the ball in towards Naismith, who clinically fires it home.

Wow! What a stunning response from Barnsley. Reece Wabara sprints down the right before setting up Daniel Crowley, who rifles the ball in from the edge of the box with a pin point finish to the bottom left corner. It's a wonderful finish from the on-loan Arsenal man.

CHANCE! Chances are coming all over the place at the minute as Everton almost make it 3-3. The ball comes it for Lukaku, but Mawson is back to clear it off the line. Barnsley immediately press back down the other end, and win a free kick in dangerous position, which Hourihane just blasts wide. What a busy few minutes it's been. And breath.

Barnsley have seen how quickly Everton can wipe out a two-goal lead, so they push for another, forcing a corner. Nyatanga rises up highest in the box to try to head it in, but it goes behind for an Everton goal kick.

Everton are on the charge again with Lukaku squaring it to Deulofeu on the edge of the box. The former Barcelona man has plenty of space and lines up the shot, but it's horribly miss hit, going high into the stand behind the goal. Meanwhile, the home supporters want a free kick down the other end as Crowley takes a tumble under pressure from Stones, but there was very little contact, so the referee waves play on.

PENALTY APPEAL! Mirallas looks the the referee as Marley Watkins wrestles him to the ground on the edge of the box, catching him around the back of the net with a high arm. The referee has been lenient throughout the night, which has resulted in a free flowing game, but that might be too lenient, as the Everton winger was definitely impeded.

There's a break in play as a couple of players need treatment. Marley Watkins appears to have picked up a knock, but Besic also appears to the struggling. The physios are working on him. Everton have already made two changes, and with 20 minutes and potentially extra time still to come, Martinez will want to keep his final change as long as possible.

Watkins is now back on his feet after also seeking attention from the physio. Here's the midfielder celebrating Barnsley's second goal of the night in the first half, surrounded by his teammates.

Deulofeu continues to try to create something for the visitors, rounding several players to make his way to the edge of the box, but Scowen is back to halt his run, forcing the Spaniard to put it out for a throw in. Roberts take the throw, and it's another impressive long-range effort from the defender, going right down the other end.

Everton come again with Barkley trying to slot the ball through to Naismith, but Wabara is closely-marking the Scot, preventing him from getting the ball away. Scowen is quick to break down the other end for Barnsley, but Hourihane can only put the finish well wide. He's struggled with a knee injury throughout pre-season, and isn't quite at peak match fitness yet.

Just like that, Everton are level again. Deulofeu plays a floated ball in from the right, and Mawson is caught watching the cross rather than Lukaku, letting the Belgian international get in space to tap in with ease at the far post.

CHANCE! Ross Barkley comes within inches of putting Everton ahead for the first time in this match as Deulofeu, who really has been busy since coming on at half time finds his fellow subsitute, who hits it first time from the edge of the box, watching it sail a fraction wide of the left post.

Barnsley were back ahead within seconds after Everton pegged them back early in the second half, and they have another chance as Stones gives the ball away 25 yards out. Hourihane lines it up, and keeps his shot low, but it's blocked by the wall.

CHANCE! Everton have come so close to a fourth twice in the last few minutes, but it's just wide again as Lukaku tees it up for Naismith, who plays it onto his preferred right foot, before striking it just wide of the left upright. Barnsley breath a sign of relief.

SUB! It's a first change for the hosts as Conor Wilkinson replaces Sam Winnall.

CHANCE! If either side are going to get the late winner, it looks like it's going to be Everton. Barkley plays the ball in for Mirallas, who sees hit shot blocked by Roberts. Barkley gets the ball away again on the rebound, but the skies it. Everton have now had 24 shots to Barnley's 10.

CHANCE! Barnsley's last-gasp defending pays off again as Lukaku rifles the ball towards the goal, only for Wabara to fling himself in front of the effort, turning it behind for a corner. Jagielka tries to get a header away from the resulting set piece, but Roberts puts it behind.

CHANCE! How many more opportunities are Everton going to get to clinch the later winner?! Lukaku turns provider as he crosses it in towards Mirallas, but the winger can only slice his finish wide.

Both sides have four minutes to try to find a winner. Everton look the more likely at the minute, but Barnsley have scored against the run of play twice already tonight.

Barnsley get the ball back down the other end for the first time in a little while, with Hourihane and Scowen playing it down the right before the latter crosses in for Wabara, but Robles is alert to the danger and claims it.

SUB! Barnsley are making a second change, with Joe Rothwell coming on in place of a limping Reece Wabara.

Barnsley just have time for one more change, as Mawson blast a long ball forward to Watkins. He collides with Oviedo, which stops him getting a clean shot away. Unfortunately for Watkins, he also appears to have taken a knock to a rather sensitive region.

Good news! There's another half an hour to come in what has been an absolutely thrilling cup tie. Barnsley showed amazing spirit to regain the lead after letting their two-goal lead slip early in the second half, but Romelu Lukaku's persistence paid off late on to force the additional period.

In fact, this was Lukaku as he scored the sixth goal of the night at Oakwell:

Over the 90 minutes, Everton had 62% of the possession, with 28 shots to Barnsley's 12.

RESTART! Everton the extra time underway.

Everton had the better of the play in the second half, so will surely want to tie this up before penalties. Deulofeu looks to create something early on, playing it through to Lukaku, who in turn finds Naismith, but the ball has too much on it, going straight through to Adam Davies.

CHANCE! Barnsley win a free kick out wide, which Hourihane curls in. Mawson manages to shake off his defender to get a header away, but he can only glance it wide.

Barnsley are pressing forward again, with Nyatanga getting forward down the right, before playing it inside for Hourihan. It eventually falls to Wilkinson on the edge of the box, who takes it inside the area before trying to squeeze it past Joel Robles at the near post. The keeper spills his stop, but Stones manages to clear it.

CHANCE! Barnsley soon find themselves back on the defensive as Lukaku plays the ball in to Naismith, who hits the ball right down the middle, but Roberts gets a touch to it, turning it behind for a corner.

For the first time this evening, Everton are ahead. The initial threat from the corner is dealt with, but Deulofeu play it back in, playing a delicate cross in to Lukaku, who has the simplest of tap ins, although the replays suggest that it might have been Marc Roberts who got the final touch. For now, it's the Belgian's goal.

CHANCE! Everton could have made it five but for a calamitous moment between Kevin Mirallas and Steven Naismith. Deulofeu plays the ball in for the Scot, but Mirallas has his back to him, not realising that the ball isn't for him, and they run in to each other, resulting in neither getting the shot away.

Barnsley have coped well since falling behind for the first time, and are keen to get back on level terms as soon as possible. Wiklinson has been quiet since coming on shortly before full time, but he wins the ball in the box, before being outmuscled by Jagielka on the turn.

Everton are well aware than Barnsley are still a danger, and they press for a fifth as Mirallas controls a ball over the top, but he can't get the shot away in time.

SUB! It's a last roll of the dice for Barnsley as George Smith replaces Marley Watkins.

So, midway through extra time and Everton are in front. Unfortunately for Marc Roberts, what at the minute would be the winner has now been awarded as an own goal, but there was really little he could have done under pressure from Lukaku while dealing with a simply brilliant ball from Deulofeu. Barnsley still have 15 minutes to turn it around.

RESTART! Barnsley get the final 15 minutes underway.

CHANCE! Barnsley make their intentions clear just moments after the restart as Rothwell picks out Scowen, but Robles holds on to his powerful strike.

OFF THE BAR! Conor Hourihane is denied by the woodwork as he curls the ball towards the top left corner, but it's just a fraction high. It would have been a spectacular finish.

BOOKING! Marc Roberts is the latest name to go in the book for a shove on Steven Naismith.

SUB! Everton make their final change, sending on James McCarthy in place of Kevin Mirallas.

CHANCE! Hourihane is showing real intent in the final part of extra time as he creates a solo effort, battling to the edge of the box before driving towards the Everton goal, only to the keeper to glance it over, giving away the corner.

CHANCE! Barnsley keep coming as Rothwell has two attempts from the resulting corner, but Jagielka blocks twice to keep Everton ahead. Scowen and Pearson already have it back in midfield though.

Wary of the Barnsley resurgence, Everton try to kill it off down the other end. Lukaku tries his luck from range, but it's a comfortable parry for Davies. Oviedo keeps the ball in place and sets up Barkley from the edge of the box, but his finish lacks power, and it straight at the keeper.

Everton have the two-goal cushion thanks to a clinical move from Ross Barkley, running from the middle to the edge of the box, dodging a couple of defenders before squaring it to Lukaku, who is left to coolly slot it in.

CHANCE! Barnsley don't think this is over yet as they press back towards the Everton goal. A probing ball into the box drops to Wilkinson, but Robles somehow manages to paw it away before leaping onto the loose ball. Smith gets it back in, forcing Stones to put it behind for a corner.

Barnsley give the ball away, allowing Lukaku to charge back towards the home side's goal. Rather than taking the shot on himself from an ever-tightening angle, he tries to repay the favour after Barkley set him up a few minutes earlier, allowing Nyatanga to clear.

There's just a minute of stoppage time to be played, and Everton are just holding the ball up in midfield to run down the clock. They've really had to work, and the home fans are giving a standing ovation to the players in the final seconds.

After 120 minutes and eight goals, it's Everton who have come out on top at Oakwell, defeating Barnsley 5-3 after extra time. It really was a gripping encounter from start to finish. Everton showed tremendous fight to get back into the match, while Barnsley just didn't give up. It was a stunning effort from both teams.

Romelu Lukaku ended up with two goals and forced an own goal. He's quickly swapped shirts with Conor Wilkinson and wears his shirt as he walks off, after handing his boots to a young boy in the crowd.

So, next up for Everton in the League Cup will be Championship side Reading at the Madejski Stadium. That's it from this fixture though, thanks for joining me this evening. Goodbye.
