Chelsea boss Carlo Ancelotti was delighted for Ashley Cole after his performance at Arsenal yesterday.
Former Gunners left-back Cole came in for abuse from his old fans.
But Ancelotti said: "Ashley was quiet before the game. He was focused on the pitch and I'm happy because he had two assists for the goals.
"Didier scored two goals and also did a very good job defending. His work maintained the balance in our team."
