Speaking on Sky, Chelsea boss Frank Lampard says: “The game was hard.
“We started really well, but the period in the second half, we didn’t get much of the ball, but Kovacic got us more on the ball when he came on.
“It felt like West Ham could hurt us at any moment; it certainly wasn’t a vintage performance tonight, but it’s good to get a win after two defeats.
“This season is different to every other season., It’s hard at a club with expectations like we have.
“When you’re winning and unbeaten for a long time things move swimmingly and it’ smuch easier to manage- but I have to be the one that drives it.
“There was a bit of tension going into the game today, in a good way, which I was happy about., They showed some real grit tonight.”
