Chelsea boss Frank Lampard admits contract talks are continuing with Willian.
Lampard has made it clear he wants the midfielder to stay.
He told chelseafc.com: "I know the club are talking to him. Willian and Callum (Hudson-Odoi) are both players I want in my squad.
"We've made some good moves this pre-season with Mason Mount and Ruben Loftus-Cheek signing new contracts, two young players nailed down and the club are always trying to do that.
"From a football sense, I've made my ideas very clear. I'm working very closely with Marina [Granovskaia, Chelsea director] and the board because these are two players that we want to stay for sure."
