The 30 year old has finally ended speculation over his future with a new contract which could keep him at the club for the rest of his career.
"I'm personally very happy and I hope I've made the Chelsea fans happy," the 30 year old told Chelsea TV after signing his new deal on Wednesday.
"I've had seven great seasons here and now I can have many more.
"It's been a difficult summer for many reasons and that was one of the frustrating things, a lot of things were said that were untrue, some things were said that were slightly true and that was frustrating.
"Now we can put that to bed and concentrate on football."
