Bayern Munich striker Thomas Muller has opened the door to leaving this summer.

Muller has been linked with Manchester United and Chelsea this past season.

And the Germany international has now declared he could be on the move.

"Another challenge would certainly be interesting and attractive," he told Welt Am Sonntag.

“If the situation is different, a lot can happen.

“Basically, it is very difficult to get away from Bayern. Currently I have no thoughts to do something else."
