Chelsea have told Manchester United they will need to part ways with Anthony Martial if they want to sign Willian this summer.
The Telegraph claims that the only way the Brazilian will end up at Old Trafford next season is if United agree to send Martial in the opposite direction.
Martial is expected to leave United this summer after failing to make an impact under Jose Mourinho.
Willian is being heavily linked with a move to both United and Barcelona this summer.
The 29-year-old fell out of favour under Antonio Conte last season and is now said to be considering his future.
The Catalan side are interested in bringing the player to the Nou Camp and it is believed Chelsea would prefer to sell to the La Liga champions.
Reports in Spain have suggested that Barcelona have already failed with a £50 million bid, with Chelsea believing they can hold out for higher as the player has two years remaining on his current deal at Stamford Bridge.
MAURIZIO SARRI TELLS MERTENS HE’LL SIGN HIM THIS SUMMER
Maurizio Sarri has vowed to sign Dries Mertens this summer, regardless of what club he ends up at.
The Telegraph reports that Sarri, who is expected to take over at Chelsea, has told the Belgian forward that he will sign him, even if that is not at Stamford Bridge.
Mertens has been touted as a possible transfer target for Chelsea this summer, but it is yet to be seen whether either Napoli or the Blues would agree to such a deal.
Antonio Conte has tried and failed to sign Mertens on two previous occasions for Chelsea, with the club deeming him to be too old.
Sarri is a huge admirer of Mertens and played a crucial role in his transition from a wide player to a central striker at Napoli.
However, Napoli are pushing to include a ‘Gentleman’s Agreement’ in the deal to take Sarri to Chelsea that will see the manager told not return to Naples in an attempt to sign any of his former players.
