Willian is yet to hear from Chelsea about a new contract.
The midfielder, 30, is about to enter the final year of his current deal.
He said: “I have one year left, but of course I want to play for this club.
“I don't know if they want me, but of course I want to continue here.
“This club is very special to me. I won titles here, I have the affection from the fans and from the people that work in the club.
“I feel comfortable to stay. I am happy when I play well and score goals. I can give a different light."
