However, Willian gave an interview where he states that he is considering leaving Fulham at the end of the season.
Per The Sun, he said: "It's true, my contract runs out at the end of the season.
"Fulham are a team I'm very grateful to, they opened the door for me so that I could return to the Premier League.
"They've also signaled their interest in me renewing my contract. I told the club that I would decide my future at the end of the season.
"For now I'm just thinking about finishing the season well, finishing playing, finishing well without injury, which is the most important thing.
And I'll decide my future that way, towards the end of the season.
"I'm open to hearing about other opportunities too, if that's the case.
"Here at Fulham I have the door to renewal and I'm very happy to know that they want me to stay here. But nothing has been decided yet and, as I said, I'm open to hearing about other options, other opportunities too."
