Maurizio Sarri is keen for Willian and Thibaut Courtois to stay at Stamford Bridge.
Speaking in his press conference ahead of Chelsea's Community Shield clash with Manchester City on Sunday, the Italian said of the Brazilian midfielder: "I spoke yesterday with him (Willian) about his lateness, not about his future.
"It was a very positive conversation. I am happy about it. There is not a Willian problem. Yes, I do (think he will stay). Very confident."
On Courtois' future, he said: "It depends on him but I hope Courtois will be our goalkeeper."
