Willian appeared certain to leave Chelsea when his contract expires at the end of this season.
It recalls that the Brazilian international recently agreed on a short-term deal to see out the remainder of the campaign with the Blues.
Speaking on his future at Chelsea, Willian told the club’s official website: “I want to finish the season well if I go, or maybe I can stay.
“I don’t know but what I want now is to play well and for Chelsea to finish in the top four.”
Willian added: “We know teams that come from behind want to win to go in the top four as well, so we have to do our job.”
