But he admits his future may lie beyond Stamford Bridge.
"I feel good," said the midfielder. "I want to play for a few more years, and I want to put myself in contention to do that.
'"I'd love to do that at Chelsea for as long as they want me and for as long as I feel I'm contributing there.
"There's a long season still to go, we're not even at Christmas yet, but I hope to keep performing.
"But again, if the time came where Chelsea said thanks very much for your service, I'd have to look at that one. I'd like to play for a few more years. Not necessarily in this country."
