The Blues face a battle with their former manager over the Brazil international who could be convinced into an Old Trafford move
Jose Mourinho and Manchester United are keen to exploit Willian's lack of first-team action at Chelsea by pushing for a summer move for the Brazil international.
Chelsea want to keep Willian, who has been in good form, despite playing a back up role for Eden Hazard and Pedro this season. Willian loves Chelsea and London but he has grown quietly frustrated with his lesser role than in previous seasons.
Willian was the first choice option under Antonio Conte for Chelsea until early October, when his mother died as the Blues winger took some time away from the first team.
