After a season of uncertainty over the midfielder's future, the Blues today confirmed the England midfielder will remain at Stamford Bridge next season.
"We've been talking for ages and even though it went on for quite a period it was always amicable.
"I want to thank Mr Abramovich for everything he's done in making the dream a reality. I love this club, the staff, the players and especially the supporters, who have treated me fantastically since the day I arrived.
"The thought of helping the club to more success in the forthcoming years is all I ever wanted. I couldn't be happier."
"We have been talking to him since the end of last year and our discussions have been entirely positive throughout.
"We are delighted we are now announcing an extension to his contract which will keep him at the club until 2014."
