Chelsea look spent here.

But there are FIVE minutes added on.

It has been a brilliant, absolutely brilliant, defensive performance by West Ham. I don't think we've seen a single defensive mistake all game.

Cesc Fabregas' ball is too strong for Victor Moses and Adrian gathers. He waves his side up the pitch.

ONE minute.

Ash Jung: This game is absolutely bad for your heart. JUST. HOLD. ON.

When Alvaro Morata missed that chance then, his manager stood on the touchline and dragged his hands down the side of his face in anguish.

Seconds later he was bending over to look at the floor in disbelief as Eden Hazard fired over.

If the champions lose this, they will be a minimum of 11, and possibly 14 points off Manchester City, which is as many as they are in front of Everton.

There would be no way back from that surely?

Another block from Aaron Cresswell - he picks off Willian's pass. He's had a very good game the defender. Cesc Fabregas' loose touch lets the Hammers boot the ball up the pitch.

TWO minutes to play plus stoppages.

The home fans roar their side on.

Stuart Pearce just kicked the ball high into the stand to waste some time! Well, you never lose it...

Stuart Pearce is sent to the West Ham bench with a ticking off by the referee as he booms a loose ball away from the waiting Chelsea players. He's not in a rush. The home fans love that. Honestly, he hammered it away.

Cesar Azpilicueta dinks over the top of the tight West Ham backline but the flag is up and Alvaro Morata won't reach it anyway.

A great run from Victor Moses in the build-up.

Antonio Conte is bent double on the touchline as if he's about to vomit. Still his side press for the equaliser.

Morata had been played played well onside and smashed the ball wide.That is the chance, that is the one Chelsea have been waiting for.

It was a one-on-one chance, and in fact Morata also missed a one-on-one in the Champions League in midweek.

Honestly, Morata will have no idea how he missed that. Adrian was rooted to the spot and just watched as the Spaniard's shot whizzed wide.

And that's another good chance wasted!

Eden Hazard blazes over from the edge after a Morata lay-off. Snatched at it badly.

N'Golo Kante - brilliant link-up with Alvaro Morata on the edge of the box.

WHAT A CHANCE.

Morata blazes wide with the goal to aim at, about 12 yards out.

Is that it for Chelsea?

Eden Hazard is dispossessed. One trick too many, or one too few.

West Ham break.

Andre Ayew can play in Diafro Sakho with a good through ball but he gets it horribly wrong.

This is the single best atmosphere I've witnessed since West Ham relocated to this massive stadium. It does help when the hosts play well...

Andre Ayew is played in by Diafro Sakho. His first touch is to drive down the line, this is a game of rugby - territory and defence - for the Hammers from here on in.

Some frustrated Chelsea fans out there feeling what their manager is acting out on the side of the pitch. Hands on hips, Antonio Conte looks edgy - a bit like his players too. This has been far from their fluid, confident best.

TEN minutes to go now.

Yousuf Ali: We lost to Crystal Palace, scored 1 against Swansea & now we're losing to West Ham. Our players go into these games thinking it'll be easy, you can't do that.

F Evans: How can there be all of these amazing attacking players on the pitch and they can’t score against a team that on average concedes 2 goals a game.

It'll be Andre Ayew coming on to replace Michail Antonio, who limps the 10 yards to the touchline.

Not a defensive move by any means that.

Michail Antonio looks absolutely spent here.

He's gone down - his legs have just given up.

David Moyes motions to the bench.

Antonio Conte cannot abide this break in play.
