More slick play by West Ham. A lovely ball forward by Dimitri Payet finds Emmanuel Emenike on the edge of the area but he is quickly closed down.

Hugo Lloris is forced into another rushed clearance after delaying a clearance from Emmanuel Emenike. 

Tottenham are out a few minutes before West Ham appear - no doubt with the words of Mauricio Pochettino ringing in their ears. Surely they can't play as badly as they did in the first half? We're back under way.

"I would not be surprised if Dele Alli comes on at half-time. Nacer Chadli has been ineffective and made the mistake leading up to the goal for West Ham."

"If Mauricio Pochettino has brought his hairdryer with him, it will be out in that Spurs dressing room at half-time.

"They have looked nothing like a team who could go top with a win here at West Ham tonight - and in fact might be happy to be only one down.

"There are still chances for them to get back in the game but they have to improve on a dismal first 45 minutes while West Ham have been everything Spurs have not, vibrant, confident and inventive."

Only one team in this. Spurs need to considerably up their game if they are to end the day at the top of the table.

Michail Antonio has the ball in the back of the Spurs net...but he's well offside. Spurs are not playing like a side that has won their previous six league games and can't wait for half-time. This has been a disappointing half as far as they are concerned.

Leicester City keeper Mark Schwarzer at Upton Park: "It’s all West Ham. Tottenham are struggling to get hold of the ball. Of the two playmakers: Payet and Eriksen, it’s all going through Payet.

“If West Ham can continue to keep Eriksen quiet then that’s half of the job done.”

Heart stopping moment for Kevin Wimmer after the Spurs defender pulls back Emmanuel Emenike as the Hammers man looked to go clean through.

Referee Andre Marriner reaches for his pocket...and it's a yellow.

Jason Murray: Spurs need to dig deep here the hammers are well up for this, games like this define titles.

Jack Foley: Slaven has West Ham purring. Glorious to watch.

All the talk before the game was about the work Mauricio Pochettino has done at Spurs, but Slaven Bilic has got his tactics spot on. West Ham are the dominant force.

More jitters from Tottenham. 

This time Hugo Lloris takes a heavy touch after a back pass and almost gifts Emmanuel Emenike a goal.

Lloris redeems himself with a comfortable save from Dimitri Payet after the Hammers player is hacked down by Toby Alderweireld, who gets a yellow card.

"Spurs showing one or two signs of life but promise has been snuffed out by some heavy touches and misplaced passes in good positions.

"Dimitri Payet is the darling of The Boleyn Ground and there is a real sense of excitement every time he gets on the ball. West Ham carry such a threat among their attacking players and the home crowd are only too keen to get in on the act."

Are West Ham heading for another clean sheet? Adrian has hardly been tested.

It's pelting it down at Upton Park.

Mauricio Pochettino is 44 today but the Tottenham boss looks thoroughly miserable glued to his seat in the dugout.

There's another mis-placed pass from his side. Poch jumps from his seat and marches to the edge of his technical area looking angry.

"I cannot understand for the life of me why Noble is not in the England squad. He has been doing it for years and people talk about Drinkwater at Leicester, but West Ham are doing well too. I think it is a joke."

Lotak: Nerve racking for Spurs fans. I'd be happy with 4 points from next two games. Got to keep positive! Dismantled them at the Lane.

Dom Signor: Really getting nervous now. What a win could do...come on you Spurs .

Avigat Patel: I want Spurs to win it but I think Man City will take it. Their squad is strong.

Spurs have looked nothing like a team challenging for the title. They are losing possession far too easily and playing second fiddle to a West Ham side that is full of zip and energy.
