Second placed Tottenham remain four points behind leaders Chelsea, who can extend that advantage to seven if they beat struggling Middlesbrough at Stamford Bridge on Monday.
Mauricio Pochettino fears Tottenham have blown their chance of winning the Premier League because they lack the ruthless streak required to succeed under intense pressure. Chelsea are going to win the league. We didn't play with the same...not intensity, but how we always play.
"If you want to be a champion you have to win. How?" Crystal Palace, anyone? Then Chelsea face a trip to West Brom, who have not been tearing up any trees recently, but you never know.
"I think you all know that now it is more hard to try to catch Chelsea".
Harry Kane had the brightest chance in the first half to shoot Tottenham ahead, but his shot was saved by the outstretched leg of Adrian.
"It wasn't our best day". "The performance was just okay". "We conceded the sort of goal you do not concede when you are a team fighting for big things".
"It's hard to be focused on Chelsea now". Spurs have just come off a run of nine consecutive wins in one of the most competitive leagues in the world which is no mean feat. And yes a little bit unlucky.
Speaking on Sky Sports on Friday night, Pardew said: "Tottenham have played the best football but Chelsea have been the best team".
The match against West Ham was a key moment.
For all the talk of its lack of atmosphere, as Lanzini smashed home the second-half victor a roar went up like nothing heard at this venue since Mo Farah came down the final straight in 2012. When asked whether the result helps to secure his own future, manager Slaven Bilic said: "I don't care".
"We deserved to win".
"Now we have to try to be ready for the next game".
Christian Eriksen, usually so composed, betrayed the anxiety creeping into Tottenham's play when he let Son Heung-Min's pass deflect harmlessly towards Adrian when a sight of goal came his way inside the West Ham area. Maybe because many topics you can add and justify why we lost.
