Bayern Munich chief Karl-Heinz Rummenigge has slammed Manchester City over their asking price for defender Jerome Boateng.
Boateng faces being priced out of a move to Bayern this summer.
"You have to look at it soberly - the player is under contract with Manchester City and the decision lies with them," he told Spox.
"They have demanded a price we will never be willing to pay.
"At the moment they're using a tactic that I've never seen: they don't respond, even if we try to contact them.
"And this is so even though they have signed two players for exactly the same position in recent days."
Rummenigge also questioned City's transfer policy.
"I think they are going to have 48 players under contract, but according to Financial Fair Play they can have only 25. And according to their last balance sheet, if I'm correct, they are minus 143m," he explained. "Maybe they still have a trick up their sleeves but I'm not sure that they will be permitted to play in the Champions League."
