Bertrand Traore replaces Loic Remy for Chelsea.
Chelsea 1-2 West Ham
What a substitution that is from Slaven Bilic! Instant impact from Andy Carroll as he makes a neat diagonal run, latches onto a cracking through ball from Dimitri Payet, and scuffs his finish beyond Thibaut Courtois. The Hammers are back in front!
Chelsea 1-1 West Ham
Andy Carroll comes on, Diafra Sakho is off.
Chelsea 1-1 West Ham
Chelsea are really trying to get the ball wide and fire it into the box low and hard at every available opportunity. This time it's Ivanovic whose centre is scrambled clear by Kouyate.
Chelsea 1-1 West Ham
And now West Ham go up the other end and nearly regain the lead! Diafra Sakho plays in the rampaging Aaron Cresswell and he rattles the bar. So close!
Chelsea 1-1 West Ham
Apologies, I missed a change at half-time - Pedro is on for Kenedy, who was impressive in the first half.
Chelsea 1-1 West Ham
Good spell for Chelsea. Willian releases Ivanovic cleverly and his low cross across the face of goal is turned behind for a corner.
Chelsea 1-1 West Ham
West Ham are under pressure here. Fabregas lofts a free-kick and John Terry heads it menacingly back across the six-yard box, but Adrian is wise to it and punches clear.
Chelsea 1-1 West Ham
Now Chelsea go close! Ivanovic whips a low cross across the face of the West Ham goal and it reaches Oscar at the back post, but the angle is tight and he can only turn it into the side netting.
Chelsea 1-1 West Ham
Ooh, has Adrian got away with one here? Remy chases a long punt forward and Adrian comes out to gather it right on the line of the penalty box. He's just about OK.
Chelsea 1-1 West Ham
Excellent start by West Ham. They break swiftly and a nice ball releases Dimitri Payet. His cross-shot from a tight angle eludes Thibaut Courtois but is cleared off the line.
Chelsea 1-1 West Ham
Back under way.

"Having been mumbling and grumbling throughout most of the first half, Chelsea'a fans are in a much more buoyant mood at the break."

Chelsea 1-1 West Ham
And that's the whistle. A disappointing end to that half for West Ham, who wasted a couple of golden chances then conceded a goal out of nothing. But they've been the better side.
Chelsea 1-1 West Ham
It looked ominous for West Ham, and so it proved. From about 20 yards out, slightly to the left of goal, Fabregas whips it up and over and beats the dive of Adrian.
Chelsea 0-1 West Ham
Winston Reid unwittingly ricochets the ball into the path of Oscar, and then decides he has to take him out. Clear yellow, and a free-kick in a dangerous position for Chelsea...
Chelsea 0-1 West Ham
There will be three minutes of added time.
Chelsea 0-1 West Ham
As Simon suggests, Chelsea haven't played with any real fluency. Willian drills a ball towards Cesar Azpilicueta, but Enner Valencia does brilliantly to get back and make the challenge.

"This has been a disjointed first half from Chelsea's point of view. There's a lack of fluidity about much of their play."
