It has been reported that Bayern Munich striker Thomas Muller would welcome a move to Manchester United this month.
The offer of €85 million has turned Muller’s head.
A United source said: “He is the one the club wants more than anyone else.
“With him in the side, United could genuinely challenge for major honours again and they are willing to break the bank to get him.
“But he will have to force the issue himself and make it clear he wants to leave Bayern. It is all down to him now.”
Muller is keen but Bayern chiefs want to keep him and are reluctant to sell a second big name to United this summer following the departure of Bastian Schweinsteiger in a £10m deal.
