Willian says he is eager to stay on at Chelsea beyond the end of the campaign but has yet to be offered a new deal by the Premier League side.
The Brazil international is into his seventh season at Stamford Bridge and is due to be out of contract next June.
But Willian, who turns 32 next year, intends to remain a Chelsea player and is waiting for discussions to begin over fresh terms.
"I feel happy here," he told reporters. "I feel happy to play for this club but the situation is not in my hands. It's in their hands.
"I'm waiting for them. They know what I want, what I want to do, so I wait for them."

Head coach Frank Lampard recently called on Chelsea chiefs to award Willian with an extension and the forward will bide his time.
"I don't want to talk to [other clubs] because I have a contract until the end of the season," he said. "I am a Chelsea player but I just want to say the club know what I want to do."
Willian made his 17th appearance of the season on Wednesday in Chelsea's 2-2 Champions League draw with Valencia, playing 80 minutes before being replaced by Mason Mount.
Daniel Wass scored eight minutes from time for Valencia to leave Lampard's side potentially needing a home victory over Lille next month to advance to the last 16.
"The end of the game was crazy and it's difficult to play at Valencia with the atmosphere," said Willian.
"At least we got a point and now we have a decider at home. I think we got a little bit lucky but it was like this so now we go to the game against Lille."
