The 25-year-old remains unhappy after being whistled by Bayern fans earlier this season.
The 25-year-old told Bild newspaper: “It was often the case in the first half of the season that I would misplace a pass in the first 20 minutes and I would be whistled at immediately.
“There were even whistles for me at the annual general meeting and that hurt.”
He added: “You never know what happens after a World Cup.
“I am really happy that we played such a good season, but to say now that I will always play for Bayern Munich would be wrong.
“Then if you do actually move, it would be an unfair proclamation to make to the fans.”
He added: “When things were not going well, we were being whistled at immediately in the Allianz Arena, but that sort of thing does not happen in England.
“I would like to have the whole stadium behind us even in difficult times.”
