The 28-year-old has played a key role in Chelsea’s Premier League title success, but has not been a regular starter, leading to reports he could be on the move.
United boss Jose Mourinho knows Willian well from his time in charge at Stamford Bridge, and reports are rife he wants a reunion at Old Trafford this summer.
United are said to have already made contact with Chelsea over a possible deal, and while it remains to be seen whether Antonio Conte would sell, Willian wants to stay.
“Yes [I will be a Chelsea player next season],” Willian told the Evening Standard earlier in the month. I have a contract with Chelsea until 2020 and I am very happy here.
“I have a great relationship with all the people that work at Chelsea and the fans too. They have been great to me since I joined.”
It is unlikely Willian has had a change of heart since then and United would face a battle to lure him away in the close season.
