The Germany defender has hinted he wants to go home a year after joining City in a £10.5million deal. But the clubs have yet to agree a fee as the Eastlands outfit are looking for around £15m.
The Germans are nowhere near. Director Christian Nerlinger said: "The player wants to go to Bayern Munich because he sees it as an outstanding opportunity.
"But Manchester City have a big price. If there is no movement from them, then I am pessimistic."
