The Brazilian international worked under Jose Mourinho when he was manager at Chelsea, and the Portuguese want him in his sides.
The 29-year-old Willian was also on the radar of Barcelona who have now opted out of the deal following their signing of Malcom from Bordeaux.
However, TuttoSport, as cited by SportWitness, is reporting that Chelsea have accepted a bid of €75million from Manchester United.
The Sun recently claimed that the former Shakhtar star has decided to leave Chelsea, despite Maurizio Sarri’s appointment as new boss.
“So, we have to wait. I’m confident.”
