Heung-Min Son was Tottenham's hero as his double sealed a crucial 3-1 win over rivals West Ham to boost their Premier League top-four hopes
Spurs took the lead inside the first 10 minutes when Kurt Zouma - who was repeatedly booed by the home crowd for his cat-kicking incident from earlier this year - diverted Harry Kane's cross into his own net (9) while under pressure from Son
Antonio Conte's side hassled and harried a makeshift back five put out by the Hammers and another swift breakaway saw Son hit the post just minutes after the opener
 But it was not long before the South Korean made his mark on the game
Once again, Kane was at the heart of the move with the England captain playing his favourite team-mate through on goal down the left, before Son slammed an unstoppable shot (24) into the top-left corner of Lukasz Fabianski's net
But despite the home side's early dominance, West Ham put out a reminder of why they refuse to go away in this top-four race
 Craig Dawson won a flick-on from Aaron Cresswell's outswinging corner, leaving Said Benhrama the simple task of a close-range finish (35) in a well-worked set-piece routine
Son made West Ham pay for Michail Antonio's missed second-half sitter when he raced through from Kane's flick-on to slot past Fabianski - and send Conte into wild celebrations on the touchline
Having distanced his side from the race for so long, Conte says that top-four qualification is now the only target going into the final run-in after the international break
"The only way to put pressure on Arsenal is to get three points and to win," Conte said
 "There are nine games to go and for us every game has to be a final
"At the moment they have a good advantage, especially because they are working with the same coach for many years and they have had many transfer markets with the same coach, maybe at this moment they are more ready than us
"But in five months we have done a fantastic job with these players and we have reduced the gap with many teams in England
"Now in our dressing room there is only one target in our mind
 I want this to happen because it is right, if you want to improve the mentality it is right to start under pressure
"For this reason I want to make this target, the race for fourth place
 We know the difficulty to reach this target
 Tottenham needs to have the ambition to play the best competition
"In England it is not simple, in this moment there are four teams that are very, very top but if one of these four teams has a struggle and then we have to try and stay there
"We know there is Arsenal that is taking advantage in the table and they are showing great stability and there is West Ham and (Manchester) United
 We want to try to fight and to have this ambition is important to ask all of the players, especially the important players because they are able to take the responsibility to show this message
"David Moyes' Hammers and their fans came into the game in dreamland after their Europa League triumph over Sevilla - but the hard load of 120 minutes on Thursday night affected their players' legs early on in this
Defender Zouma was warned about his sloppiness when he gave the ball away cheaply on two occasions ahead of Spurs' opener, before his team-mate Cresswell gifted the home side the early advantage
Cresswell's poor pass out from the back was picked up by Matt Doherty, who fed Kane to cut a low cross into Son's path
 The forward was ahead of the ball in but Zouma did the work for him with his outstretched leg making contact with the ball and sending it past Fabianski
Kane nearly went from hero to zero as his slack backpass was picked up by Antonio, who flashed a shot wide inside the box when he should have done better from the right of the area
But back came Spurs and Dejan Kulusevski went on a brilliant solo run, with his cross finding Son who struck the outside of the post
The South Korean went one better midway through the half as a brilliant turn and through ball from Kane found him down the left channel
 Spurs' No 7 stood up Zouma, who allowed a shot across Fabianski's goal and it was a sumptuous finish into the top corner
That was the 38th time Son and Kane have combined for a Premier League goal, with the England captain now on 51 top-flight assists
 Kane also has a goal or an assist in six out of his last seven Premier League matches
But Tottenham rested on their laurels and failed to add to their advantage which allowed West Ham a route back in
Dawson beat four Spurs defenders underneath Cresswell's delivery and that aerial win was crucial for Benrahma to latch onto the ball and slam past Hugo Lloris from six yards out
West Ham were relieved to go into the break still in the contest but Tottenham tried to turn the screw after the break
 Son led a counter-attack before slipping Kane through on goal, but Fabianski did well to get to his feet and deny the striker his sixth goal in five matches
The momentum from that chance was halted as two protestors ran onto the pitch and tried to attach themselves to the goalposts, in replica scenes to Everton's stoppage against Newcastle on Thursday, and West Ham grew into the game
Antonio wasted another chance when he blasted Cresswell's cross wide from around eight yards out, before being replaced by Andriy Yarmolenko, who fired into the side-netting down the left within minutes
As the second-half clock ticked on, West Ham began to tire after their European exploits - and their opponents took control
 Spurs cried for a penalty when yet another Kane throughball saw Sergio Reguilon collide with Ben Johnson, but referee Anthony Taylor waved away the home side's complaints
 Spurs' front three then combined, resulting in a shooting chance for Kulusevski, who fired over
Despite his excellence in giving the ball in crucial moments, Kane then spurned a major opportunity to put the game past West Ham with 10 minutes left
 The Spurs talisman remained onside and was played through from a dink over the top, but could only prod over
But that wasted opportunity did not matter as Son raced through after Kane flicked Lloris' goal-kick on for a one-on-one to seal the three vital points
With the result sealed, Spurs' faithful rose to their feet to salute Conte with chants of "Antonio, Antonio", with the full belief they can get a top-four finish and a seat at Europe's top table for next season
For West Ham, the endeavours of Thursday night ultimately caught up with them but Moyes was more disappointed with the sloppy way his side started the game
"It's the opening part of the game that showed it [the tiredness]," Moyes told his press conference
 "I'm incredibly disappointed
 If you're the Under-11s coach you would be disappointed with it
"You could not have picked a worst game [at the end of this big week]
 It's incredibly difficult because Harry Kane is an absolutely world class player and if you don't get it right… we didn't quite get it right
"Things look a lot brighter in north London, and it's not just the weather
 The cold winds from a few weeks back have well and truly gone but a chilling message has still been sent through the air in this area's divide
Tottenham are getting their act together and Arsenal should be worried
 Now Antonio Conte's side are breathing down their neck and are within one strike of the Gunners until the middle of April at least
A lot of the plaudits after Sunday's result will surround the deadly duo of Kane and Son - whose forms since the start of the calendar year have looked as good as ever
 Cristian Romero is becoming a leader at the back and the January additions of Kulusevski and Bentancur are paying off
Given Spurs have shown the same defensive resilience that Arsenal have showed at Villa in recent game, plus the fact that Lucas Moura and Steven Bergwijn are barely used in Conte's team, you could argue Tottenham are stronger than the Gunners in terms of squad depth
Then you look at the April fixture list
 In their five games, Spurs play no team higher than ninth in the table
 Arsenal are away from home for most of that run, with Chelsea and Manchester United on their agenda
Throw in a north London derby scheduled for May and Spurs are in good stead
 Given the atmosphere from the West Ham derby, Mikel Arteta will ideally not want to take his players to Spurs needing a result
The mind games have already started when it comes to Conte and Spurs
 While there is a pressure for the white half of north London to keep up with the Gunners, Conte hinted that Arsenal have no excuse to throw their various advantages over Tottenham away
"The only way to put pressure on Arsenal is to get three points - to win," Conte said
 "There are nine games to go, every game has to be a final
"For sure they have a good advantage also especially because they've bene working with the same coach for many years
 They have had many transfer market with the same coach, maybe they are more ready than us
"Let battle commence
