Midfielder Tim Borowski has admitted he is unhappy after failing to hold down a starting place at Bayern Munich.
The 28-year-old Germany international swapped Werder Bremen for Bayern last summer but has yet to establish himself as a first-team regular at the Allianz Arena.
"I'm really upset with my current situation," said Borowski.
"I was in an excellent form before the winter break and I was one of our better performers. However, for some reason I've lost my spot in the starting eleven.
"I can't accept the way things are going at the moment and I want to discuss my future if nothing changes in the upcoming weeks.
"I didn't come to Munich to warm the bench. Nevertheless, leaving the club isn't an option for me at the moment.
"I'm proud to be a Bayern Munich player and I want to prove my worth."
