A remorseless Tottenham Hotspur may have driven the final nail into Russell Martin's Southampton coffin as the Lilywhites slaughtered the Saints 5-0 at St Mary's in the Premier League.

Flashbacks to the 9-0 Manchester United and Leicester City annihilations may have been triggered for the home crowd in the first half, where Ange Postecoglou's men mercilessly ripped their hosts to shreds and achieved a slice of club history in the process.

Thanks to James Maddison's brace, Son Heung-min's strike, Dejan Kulusevski's effort and Pape Sarr's goal, Tottenham scored five goals in the first half of a Premier League game for the first time ever, although a large portion of crestfallen Southampton fans had already left by the time it was 3-0.

In a turn of events that should have surprised absolutely nobody, the game slowed to a crawl in the second half, where Tottenham conserved their energy and sent on the kids while Southampton's Mateus Fernandes had a consolation disallowed for offside.

Tottenham scored as many goals tonight as Southampton have points on the board all season, and Martin's men remain cut adrift at the bottom of the Premier League table, while Spurs have sneaked back into the top half thanks to Chelsea's success over West London rivals Brentford.

SPORTS MOLE'S VERDICT

Sunday's St Mary's showdown may have been a clash between two managers under pressure, but while Postecoglou would almost certainly have not been sacked had his side suffered a shock loss, the end is surely nigh for Martin.

In a last-ditch bid to find a winning formula, the Southampton head coach opted for a 4-3-1-2 diamond setup, which went spectacularly awry to the point that he sacrificed the understandably furious Kamaldeen Sulemana for an extra defender with just 15 minutes gone.

Martin heading for the dressing room before half time and missing Maddison's goal made the evening all the more embarrassing for him and the team, and it must be only a matter of time before the inevitable 'Club statement' social media post is put out on Southampton's channels.

As Southampton continue on a one-way street back down to the Championship, a hitherto tepid Tottenham must use this emphatic success as a springboard for an upturn in festive fortunes, as they desperately try to escape mid-table mediocrity.

Postecoglou's side will undoubtedly face tougher tests in the weeks and months to come, but their first-half ruthlessness, Djed Spence's immediate impact and Son continuing his love affair with Southampton were all sights for sore Spurs eyes.

SOUTHAMPTON VS. TOTTENHAM HIGHLIGHTS

James Maddison goal vs. Southampton (1st min, Southampton 0-1 Tottenham)

A harbinger of doom for the Saints? Tottenham strike after just 36 seconds, as Spence charges infield from right-back before finding the run of Maddison with a slick outside-of-the-boot pass.

The Tottenham playmaker clinically does the rest, firing a low strike underneath the onrushing Alex McCarthy and into the far side of the net.

Son Heung-min goal vs. Southampton (12th min, Southampton 0-2 Tottenham)

Another game against Southampton, another goal against Southampton! Son boasts more goals against the Saints than he does against any other team, and the Spurs skipper has now struck for the 13th time in this fixture.

Jan Bednarek can only head an outswinging deep cross to Son at the back post, and the South Korean has ample time to let the ball bounce twice and lash home a powerful half-volley

Dejan Kulusevski goal vs. Southampton (14th min, Southampton 0-3 Tottenham)

The boos grow louder, and the exodus begins! A handful of disgruntled Southampton fans are already making a beeline for the exits as Kulusevski makes it three for the merciless visitors.

Bednarek does enough to prevent Dominic Solanke from tapping in Son's cutback, but the rebound falls kindly for Kulusevski, who was abandoned by Ryan Manning and could not miss on his 100th Premier League appearance.

Pape Sarr goal vs. Southampton (25th min, Southampton 0-4 Tottenham)

Martin immediately changed Southampton's system after Kulusevski's strike, albeit to little avail, as Sarr triggers another cacophony of boos from the St Mary's faithful with a tidy finish.

Son is heavily involved once again, cutting inside from the left and finding Sarr, who dances past Nathan Wood and is about to fall on his backside but manages to hook the ball into the bottom corner.

James Maddison goal vs. Southampton (45+5 min, Southampton 0-5 Tottenham)

Does anybody have that Simpsons 'Stop! Stop! He's already dead!" GIF?

A goal made even more embarrassing for Southampton by the fact that Martin did not even see it; the Saints boss had already trudged down the tunnel to prepare for the biggest half-time team talk of his life.

In his absence, Son releases Maddison into the left-hand side of the box with a wonderful pass, and the Englishman manages to find the far side of the net from an incredibly tight angle.

Spurs had never scored five in the first half of a Premier League game before today, but Southampton were only too happy to oblige.

MAN OF THE MATCH - SON HEUNG-MIN

Son did not quite emulate his four-goal haul at St Mary's from September 2020, but the Tottenham captain needed just 45 minutes to make three telling contributions, notching Spurs' second with a crisp half-volley and also laying on two helpers for Sarr and Maddison.

In doing so, Son drew level with Darren Anderton on the most Premier League assists for Spurs - a staggering 68 - and he count count himself unfortunate not to have bagged a brace or even a hat-trick, having also hit the woodwork and had seven shots in total.

WHAT NEXT?

Liverpool in the EFL Cup quarter-finals on Wednesday evening is next up for Southampton on the field, but whether Martin is still in control of the reins when the league leaders come to visit is anybody's guess.

However, Postecoglou will certainly be leading Tottenham into battle against Manchester United in Thursday's cup encounter, before the Lilywhites engage in their own mouthwatering Premier League match with Liverpool on December 22.
