Riyad Mahrez, who had earlier come close on two occasions, made the breakthrough on 34 minutes when he slotted home from Jamie Vardy’s assist.

Aaron Cresswell nearly restored the Hammers’ lead just before the hour mark, but his cross-shot came back off the crossbar.
Slaven Bilic’s men were soon 2-1 up, though, when Andy Carroll latched onto Dimitri Payet’s pass and thumped a shot past Thibaut Courtois in the Chelsea goal.
