Thomas Muller believes the numbers being speculated surrounding his potential move to Manchester United are 'crazy'.

The Bayern Munich star has been linked with a summer shift to Old Trafford with some reports suggesting the Red Devils could pay as much as £100million for his services.

When quizzed by the German media, Muller did not give too much away regarding a possible move to England but did admit the rumours were a little nuts.

"It's basically crazy the numbers which are currently kicking around in football. That's just business," Muller said.

"In Dresden, a fan addressed me with a megaphone: 'Hey €100million man, what is your playing shirt worth?' That made me smile."
