Speaking at a press conference, however, Sarri, who also spoke about Willian's late arrival back to Chelsea, confirmed that he had a "positive conversation" with the player.
"I spoke yesterday with him about him being late, but not about his future," the manager said. "It was a very positive conversation. I am happy about it. There is not a problem with Willian."
When asked if he was confident that Willian would stay in West London, Sarri replied: "Yes. Very confident."
The winger has two years left on his current Chelsea deal.
