Chelsea boss Maurizio Sarri has no doubts Willian will stay at the club - but is unsure where Thibaut Courtois' future lies.

Sarri says he had a "positive conversation" with the player on Thursday.

"There is not a Willian problem," said the former Napoli boss.

"At the moment Courtois is the goalkeeper of Chelsea," said Sarri.

"I don't know in the future. It depends on the club, it depends especially on him, but I hope Courtois will be our goalkeeper."

Discussing the futures of Brazil centre-back David Luiz and England forward Ruben Loftus-Cheek, Sarri added: "I am very happy with David for his attitude. I think he will be very important for the team.

"Loftus-Cheek I have only seen three or four [times in training], so I will have to wait".
