Chelsea are willing to let Willian join Manchester United as long as they get Anthony Martial from their Premier League rivals.
Willian has been heavily linked with a move away from Stamford Bridge this summer, with Barcelona and United mooted as possible destinations.
Jose Mourinho is in the hunt for a winger and is a big fan of Willian, with whom he previously worked with at Chelsea.
According to the UK Telegraph, the Blues will only let Willian move to Old Trafford if Martial is included in the deal.
Last month, Martial’s agent confirmed that his client wants to quit the Red Devils, after falling out of favour under Mourinho.
“After thinking about all the possibilities and settings, Anthony wants to leave Manchester United,” Philippe Lamboley told RMC Sport .
