Willian is being linked with Barcelona.
But Sarri says: "Willian, for us, is a very important player. As I said yesterday in the press conference, in my opinion he has to stay with us. He's very important player, like Pedro.
"Hudson-Odoi is becoming a very important player so with Eden like a striker today, we need wingers, so we need Pedro, Hudson-Odoi and Willian, of course. At this moment he's a fundamental player."
