Chelsea hero Ashley Cole was impressed by their performance in defeat at Liverpool on Sunday.

Cole believes it was Chelsea's best team performance under Sarri, but was eager to point out that there is still room for improvement.

Speaking on Sky Sports, Derby County fullback Cole said: "I think it should feel different for them.

"It's the best I've seen them collectively as a team. They kept the ball well, they created chances and Jorginho in the first half played very well - he got around players, made important tackles and freed Willian in behind.

"At a club like Chelsea, it shouldn't really matter how well you're playing, you've got to be winning games. You can't be losing big games like this. For next season they have to finish top four."
