Chelsea manager Frank Lampard:
"I thought we were great. I'm pleased because that was us again, we had a blip against West Ham and today we were back.
"Our character at half-time was important and we carried off where we left off. The disappointment of the day is we score two or three.
"Villa are stubborn, have picked up results on the road and you can see why. They have good players and are well organised."
"I thought it was a fair result, the better team won.
"We had pockets of play throughout the game but not enough relentless pressure. We didn't start either half well and they put us under pressure. We gave the ball away too cheaply, but got back into the game and when we showed a bit of belief we showed we could give them problems.
"They had the initiative, we knew they would start well after losing a London derby on Saturday.
"You don't get much from officials here and I wasn't happy with their performance tonight. Jack Grealish must have been the most-fouled player on the pitch, there were five or six not given."
