Franz Beckenbauer has fired a warning at Toni Kroos over his contract demands at Bayern Munich.
Manchester United are waiting to pounce as Bayern refuse to meet Kroos' terms.
Bayern honorary president Beckenbauer told Sky: "You have to make a decision as a club when someone's demands are going through the roof.
"There is not a single player who's worth changing your entire wage structure for.
"Nobody's indispensable. If the player wants to stay at Bayern, I can only advise him not to overplay his hand."
