Fulham boss Marco Silva has hopes of keeping hold of Willian.
The midfielder's deal is due to expire at the end of next month.
Silva said: “At the end of the season — like I did with him last season — we are going to analyse the season and see together.
“It's what he would like to do. Of course, we respect that. Me, myself [and] Fulham would like him to have another season with us."
Fulham have also offered Kenny Tete a new deal.
Silva said: “There are three [possible] solutions for him. We have been talking with him. Some moments the conversations were more hot — at moments close, at moments not so close.
“We have an option in the contract that we can trigger. [Between] us and Kenny, we are going to come to a decision."
