Alexis Sanchez scored twice to help Arsenal to a vital 3-0 win over Dinamo Zagreb in the Champions League this evening.

The Chilean forward found the net either side of half time to add to Mesut Ozil's earlier opener, ensuring that the Gunners' hopes of progression remain intact.

It was a quiet evening for the home side's backline, although Petr Cech did have one big save to pull off to keep a first clean sheet in four outings.

Here, Sports Mole runs the rule over both teams to see how each player performed across the 90 minutes in North London.

ARSENAL

Goal

Petr Cech: A very quiet night for the experienced stopper, bar a fine late save to his right to push aside a shot that deflected off Flamini on its way through. (7/10)

Defence

Hector Bellerin: Did take a while to grow into the game, but when he did find his stride the trademark bursts and smart link-up play started to shine through. (6/10)

Per Mertesacker: Never truly troubled at the back, yet Zagreb had a number of corners throughout the match - including three in the opening nine minutes - which the big German dealt with efficiently enough. (6/10)

Laurent Koscielny: Was given the responsibility to make a couple of runs forward into midfield which, other than a couple of stray passes, he did well on the whole. (6/10)

Nacho Monreal: Did everything that was asked of him at the back, while also reading things well up the other end of the pitch to pounce on a loose pass and play in Sanchez for the second. (7/10)

Midfield

Joel Campbell: Looked a real threat when on the ball, perhaps being boosted by the knowledge that Aaron Ramsey is now back in contention. The Costa Rica international's defence-splitting pass for the third goal provided the best attacking moment of the night. (8/10)

Mathieu Flamini: Another player who simply did what was asked of him, sitting deep and playing the role that Francis Coquelin has made his own over the past year. (6/10)

Santi Cazorla: Much improved following a few underwhelming displays either side of the two-week international break. Far from his best, in truth, but still proved key by keeping things ticking over in the engine room. (7/10)

Mesut Ozil: Given far too much space to run the game from midfield, which he used to his advantage when bursting forward and heading home the opener. Ozil has now been involved in nine of Arsenal's last 12 goals. (8/10)

Alexis Sanchez: Laid the ball on a plate for Ozil's opener, before finding the net himself on a couple of occasions. Both goals were smart finishes, with the latter seeing him latch on to Campbell's through-ball before coolly rounding the keeper. (8/10)

Attack

Olivier Giroud: The Gunners' weakest attacking player on the night, failing to really get himself involved prior to being taken off 25 minutes from time. (5/10)

Substitutes

Aaron Ramsey: A first run-out for the Welshman since limping off against Bayern Munich six weeks ago. A welcome return for Arsene Wenger, who has seen his side struck down by a number of injury problems yet again of late. (7/10)

Calum Chambers: Brought on in the closing minutes as Wenger looked to utilise his full group of players. (5/10)

Mathieu Debuchy: A similar case for the French full-back, who made just his eighth appearance of the campaign late on in North London. (5/10)

DINAMO ZAGREB

Goal

Eduardo: Did not have a single shot to keep out prior to Arsenal's opening goal, but was then called into action with two big stops before the interval. Conceded three times but did produce a decent enough performance overall. (7/10)

Defence

Ivo Pinto: Came out second best in his personal battle down that right flank, being left exposed at times when one on one with Sanchez and Ozil. (6/10)

Leonardo Sigali: Was at fault for the Gunners' second goal, inexplicably passing the ball straight to Monreal who did the rest. (4/10)

Jeremy Taravel: A few last-ditch challenges were required but he struggled to deal with Arsenal's attacking threats across the full 90 minutes. (5/10)

Alexandru Matel: Barely ventured forward until seeing his side fall three goals behind. Looked lively when he did get into advanced positions, dragging a deflected effort narrowly wide of goal. (6/10)

Midfield

Marko Pjaca: Struggled when it came to tracking Monreal down the wing and, while he did show a few good touches, there was nowhere near enough attacking threat from the Zagreb man. (5/10)

Paulo Ricardo Machado: Another who struggled when it came to his attacking duties, instead being more concerned with trying to halt the opposition players. (5/10)

Goncalo: Looked as though he was given the task to thwart the threat of Ozil, which he did not exactly succeed in doing. (5/10)

Domagoj Antolic: Produced a fine tackle to deny Arsenal on the break, and looked to be one of the visitors' better players. Was an injury doubt coming into this one, though, so no great surprise to see him taken off early. (7/10)

Attack

Junior Fernandes: Offered some pace but did not utilise it enough to get in behind the Arsenal backline. (5/10)

Marko Rog: Was given the thankless task of trying to lead the attack, with support into his path non-existent. Essentially a midfielder, but has not scored in 13 appearances this term. (5/10)

Substitutes

Ante Coric: A young player who is highly thought of back in his homeland, the 18-year-old was brought on for the final few minutes to aid his development into a potential star. (5/10)

Angelo Henriquez: Replaced Antolic 20 minutes from time but was unable to truly help turn the game in his side's favour. (5/10)

El Arbi Soudani: Provided some attacking impetus in the final quarter of the game yet, while Zagreb did enjoy their best period in those final 25 minutes or so, the opposition defence still had very little to do in the grand scheme of things. (6/10)
