Chelsea boss Maurizio Sarri speaking to BBC Sport: "Today was very important to get points. We started well but after the goal we slept for 20 minutes, so by the end of the first half we were in trouble.
"We were better in the second half. I'm very happy with the result but we need to improve mentally and technically because we lost a lot of the ball in a stupid way.
"I think our wingers attacked the space better than in the last five or six matches but we need to attack the box better."
