The 32-year-old former Germany international, who moved to Old Trafford in July 2015, has not featured this season under new United manager Jose Mourinho, with reports suggesting he has been made to train with the reserves.
But the World Cup winner took to Twitter on Wednesday to stress his commitment to the team.
"MUFC will be my last club in Europe," he posted
"I respect other clubs, but Manchester United was the only one which could make me leave Bayern Munich.
"I will be ready, if the team needs me.
"That is all I can say about the current situation
I want to thank the fans for the amazing support over the recent weeks."
