Chelsea boss Antonio Conte has told Willian to work harder to win back his place.
The Daily Express says Manchester United boss Jose Mourinho is planning a £25million move for the Brazil winger.
Conte has sent Willian a message and told him to knuckle down.
“Willian has come back and now it is important to find good form because in this period he was unlucky,” Conte said.
“I don’t know why. But now it is important to focus on the work and training sessions.”
