Don't listen to the media. There is no "crisis" at Bayern Munich over Thomas Müller. He hasn't demanded a transfer from the club. There hasn't been a falling out with Pep Guardiola. Pep also hasn't told Müller that he can leave. None of these things have happened.
What has happened?
Karl-Heinz Rummenigge said, "Thomas is not for sale", after saying that he was a player without a price tag.
Then, two weeks later, Rummenigge reiterated this fact. "Louis van Gaal is very stubborn, but there is no price for Thomas Müller."
During Guardiola's press conference before Bayern's match against Hamburg, he was asked about Rummenigge's statement that Müller (And Mario Götze, for that matter) would be staying in Munich. His response was, "I already knew that two or three weeks ago, so it's not news to me."
Now, according to Sport Bild, Manchester United have made another offer for Müller. This time, it's in the amount of €85 million. This offer, like every other offer they've ever made, was rejected without even a second thought. Bayern have no interest in selling him.
The only thing that is for sure is that Manchester United currently reeks of desperation. Since joining the British club in the summer if 2014, Louis Van Gaal has splashed nearly €325 million to bring transfers into the club. Last season, Manchester United finished in fourth place, a full seventeen points behind champions Chelsea.
So, signing him, or at least giving the impression that they have the potential to once again sign a player with the quality of Müller, is the most important thing for United to accomplish at this point in time.
Thomas Müller will only leave Bayern Munich if two things happen. He has to demand a transfer. The other club also has to present Bayern with the largest transfer fee in the history of sport. If both of these things were to happen, Bayern would consider selling Müller.
It's time to get over it, Manchester United.
