Willian, 28, has struggled for regular game time since Antonio Conte’s arrival at Stamford Bridge.
The Brazilian has started just 13 Premier League matches under his new boss this season.
According to the Daily Mail, he could seek a move away from west London this summer.
And they claim Manchester United are among his potential suitors.
Jose Mourinho knows Willian well from their time together at Chelsea.
He parted with £30m to sign the midfielder from Russian outfit Anzi Makhachkala during his second spell as Blues boss in 2013.
Willian is tied to Chelsea until the summer of 2020.
He came off the the bench to score as Conte’s men claimed a crucial 3-0 win over Everton this afternoon.
