Chelsea boss Jose Mourinho hailed the performance of Cesc Fabregas for their 2-0 win over Arsenal.
Fabregas, playing against his former club, set up Diego Costa's goal.
Mourinho said: "Fantastic (performance). But to be fair he didn't have this performance because the opponent was Arsenal and he had a special motivation.
"He's been doing this since day one. I don't remember a game this season where he was not fantastic.
"To play against his team, the team where he was born or made for football, I think shows even more his commitment with us and his professionalism."
