Former Manchester United defender on Radio 5 liveI think Gary Cahill has been Chelsea's best player. His distances have been superb, he's defended brilliantly.

Robert Snodgrass picks the ball up wide left and fires a dangerous cross which no-one is on hand to meet. At least it's drawn a little enthusiasm from the home fans.

West Ham 0-2 Chelsea
In Andy Carroll's defence, he's lonely. When he does make any effort to close down the Chelsea back three play around him and he has no support to pressure them.

West Ham 0-2 Chelsea
West Ham are just a bit frustrating really. When Chelsea get the ball there is no urgency to unsettle them at all. Andy Carroll walks around at a time where most fans would want their striker sprinting to make something happen.

Former Manchester United defender on Radio 5 liveIt was a training ground goal. It was whipped in by Hazard, inadvertently flicked on by Pedro Obiang and Costa kneed it in.
It was a brilliantly worked goal.

Marcos Alonso shows footwork like Maradona in his prime, skirting two challenges on the edge of the box with a quick dance and suddenly he's in. Darren Randolph shapes to rush out so Alonso lifts his effort but it dribbles wide. Could have been three.

Diego Costa
Game over. Turn out the lights. Go get the tube. Put the kettle on back at home. Run a bath with your smart phone if you're that tapped into technology.
A simple, simple goal. Diego Costa knees the ball over the line from four yards. Eden Hazard's corner is flicked on by a West Ham player - I think it's Pedro Obiang - and Costa cannot miss.
The corner was won as a result of another break away. Chelsea just ruthless.

Eden Hazard just back-volleyed a pass to someone. That's right, a floating ball, nudged with his back into a team-mates path.

N'Golo Kante gives the ball away.
I'll say that again as he's typically beyond criticism: N'Golo Kante gives the ball away.
Mark Noble plays Robert Snodgrass down the left and his cross wins a corner. That was a dangerous loss of possession from the Chelsea energy ball.

Again West Ham begin by dropping off, Andy Carroll stays on the halfway line. Pedro Obiang breaks play up but there's nothing for Manuel Lanzini to play forward to. His clipped pass gets Carroll chasing hopelessly.

We are under way again. A big 45 minutes for Chelsea, this could be a tricky fixture off the slate and a very, very handy result.

West Ham 0-1 Chelsea
For a half which was even in terms of possession and shots, West Ham had just two touches in the area (left).
Their use of the ball in the final third was almost totally focused on crosses in towards Carroll. Somehow they need something different. Andre Ayew is on the bench of course.

So how are you feeling Tottenham fans? Is this a league-clincher of a result?

Former Manchester United defender on Radio 5 liveChelsea boss Antonio Conte won't be happy with his team. They should be two up, maybe three. He'll tell them to be more ruthless with their counter-attacking, at half-time.
The consolation for West Ham boss Slaven Bilic is that his side are still in the game.
