Mauricio Pochettino has vowed not to repeat the same mistake as Tottenham take on London rivals West Ham.
On the Hammers last trip to Wembley, they staged an incredible comeback to dump Spurs out of the Carabao Cup back in October.
Tottenham haven't lost a game at their temporary home since and boss Pochettino insists his top-four chasing side will be ready for David Moyes' men.
Should the 16th-placed east London side beat Spurs again, they will jump up to 11th in the Premier League. Three points for the hosts would move them to within a point of fourth-placed Liverpool.
So, who will come out on top?
The game is live on Sky Sports and available for Sky Go and Now TV subscribers to live stream.

West Ham move up to 15th now, two points ahead of Stoke in the relegation zone - though all parties concerned now turn their attention to the FA Cup. The Hammers will travel to Shrewsbury on Sunday, looking to avoid an upset - and likewise, Tottenham will entertain AFC Wimbledon at the national stadium, hoping for smooth progress. Until then, thank you very much - and have a good weekend!
After a first half to forget for both sides, Wembley was sparked into life on a wet and windy Thursday night by two absolutely incredible goals, from Obiang of the Hammers and Son of Spurs. Tottenham may have recorded 27 shots to West Ham's 3 - but a superb resilience led by Adrian in goal saw the visitors hold the hosts to what could be a vital point in their relegation battle. Full-time in North London, it finishes Tottenham Hotspur 1-1 West Ham United.
Into the final minute of added time, and Lamela crosses into the box for Kane. It comes off the arm of Zabaletta - and Spurs all shout for a handball. Referee Mike Dean waves it away - and Reid punts downfield. Lloris returns long, and Reid clears again. The keeper goes for another long punt - but the clock ticks over and the full-time whistle goes! West Ham hold Spurs to a draw at Wembley!
Can West Ham hold on for a well-deserved point? It's been a near masterclass in goal from Adrian tonight - but he will have to withstand another attack as Son cuts down the right. He's pinned by Rice before he can get the cross away and Masuaku earns a throw.
Tottenham bust through the West Ham defence again, though Obiang does just enough to cut in between Son and Kane to deliver an escape for the visitors.
A silly tackle from Noble on Llorente on halfway sees the Hammers man booked and gives Tottenham a free-kick. Four added minutes incoming.
Overall Possession Ratio
Possession
Carroll looks to be through on the left with a long ball returned from Reid, only to be pulled for offside. He kicks the ball away in frustration and is booked for his troubles.
Wanyama absolutely blows a shot in front of goal as West Ham fail to clear and Zabaletta looks to get it away, only finding the midfield before Llorente pins his advance back.
Lanzini is off for West Ham - and the hero of Tuesday night Andy Carroll is on. Can he snaffle a winner for the Hammers?
What a beauty that one is too! Tottenham level through Son with another absolutely superb strike, the Spurs man picking out a flat pass 25 yards out and burying it in the top right corner. What a way to come back into this game. All square at Wembley with six minutes and added time left.
Lamela's pass was the perfect set-up for Son, giving him the space and time needed. What a goal. What a fabulous goal.
Eriksen curls it in and Rice clears as far as Vertonghen who launches his own shot, deflected off Ogbonna. Another corner...
Davies is the final change for Spurs with Fernando Llorente taking to the field as we await this corner...
Rice puts a long ball from Lamela out for a corner to prevent Kane from getting near it. Corner to Spurs then...
Nervy times for the Hammers as Adrian bobbles and manages to hold onto a Son cross aimed across the face of their box for Kane or Wanyama.
Fine rain is coming down in North London now and it's starting to get a bit slippy underfoot. Eriksen goes close again, stuttering on the edge of the box before shooting - and Adrian once more swoops down on the ball as it heads towards him.
Free-kick to the Hammers some 40 yards out on the right. Lanzini swings it in - and Kouyate almost adds a second goal! The midfielder's header leaves much to be desired after he escaped the man-marking of Davies; that could have added a cushion for the visitors they desperately need.
Eriksen scythes into the box on the left, and this time drills low; Adrian manages to angle himself just right to catch the awkward bounce on the turf as the shot comes in from 18 yards out.
Spurs immediately mass forward to try and find a leveller and earn a corner as Kane puts a short ball to Adrian that is tipped out on the right side of goal. Eriksen's effort finds nobody - but moments later, Kane launches another shot after retaking the ball from Rice, only 12 yards out in front. Again, the keeper holds him off with a deflection and Ogbonna clears with a volley.

...and Dier makes way for Victor Wanyama.
Double change for Spurs now as Sissoko is replaced by Erik Lamela...
Kane again! He manages to bulldoze through the back line and only has the keeper to beat; except Adrian manages to block him once more at close range. Alli goes up for the header and is taken out by Adrian somehow making a second challenge; again, penalty cries are waved away.
It was a lovely cut-back pass from Lanzini to set up Obiang's strike - and what a strike it was. A world-class finish.
Wow, what a goal from Obiang! Having registered no shots tonight on goal, West Ham take the lead with an absolutely stunning effort from the former Sampdoria man, who launches a wonderful curling strike from 20 yards out on the left that loops into the near top corner despite the efforts of Lloris. Against the run of play, the Hammers hit the front at Wembley.
Eriksen is the latest man to chance his arm, putting a close range shot from the left edge of the box that Adrian dives to scoop up. Shots flying in from all over now from Spurs.
Chicharito is the first man to depart Wembley tonight as Andre Ayew replaces him for West Ham.
It's another chance for Kane, who this time slips in between Reid and Ogbonna, only for Adrian to smother his strike and force the England man to put his follow-up wide. The West Ham keeper is delivering the goods in goal tonight, even when his defence isn't.
