He said: "If I was to finish my career at Chelsea, I'd be delighted. I have played well this season and it will be my best for the club if we win something.
"But the next five to six years will see the best of me. Hopefully I will play for a long time because I am not someone who relies on pace. I'm someone who always puts his heart and soul into every game I play. I'd hate to ever fall out with the fans or for anything to go wrong.
"I have a great relationship with the fans and it is great to be playing under a manager who really believes in me."
