Bayern Munich general manager Uli Hoeness has admitted that Willy Sagnol has fallen out with coach Ottmar Hitzfeld.
The French international defender suffered a serious knee injury against Milan in the UEFA Champions League quarter-final in April, but since regaining fitness he has found it difficult to break back into the team.
As a result of Hitzfeld's continued reluctance to restore him to the first team, Sagnol has stated his desire to leave the club during the winter break which starts on December 15.
The news comes as a surprise as Sagnol was widely tipped to take over the club captaincy when Oliver Kahn finally decides to hang up his gloves.
However, with Euro 2008 approaching the defender is concerned about losing his place in the French national squad if he is failing to play regularly at club level.
Whilst admitting the differences between the player and coach, Hoeness insists that it is not yet certain that Sagnol will leave the club.
"There are at present some problems between Willy and Ottmar Hitzfeld, differences of opinion over his fitness and we hope that they will be resolved during the winter break," said Hoeness.
"We will discuss the situation and hope to try and resolve it, but if we can't then we will have to look at the options and make a decision.
"I would not like to anticipate what that discussion will lead to."
As one player may be on his way out of the Allianz Arena in the near future, Bayern president Franz Beckenbauer has hinted that there may be more stars on their way in.
Brazilian teenager Breno is expected to sign for a reported 14 million euros from Sao Paulo during the winter break, and more defensive cover may arrive in an attempt to shore up a defence which has looked far from secure at times this season.
