Bayern Munich captain Mark van Bommel has not ruled out leaving the club this winter, six months before his contract is due to expire.
The Dutchman is unlikely to be offered a new deal for next season by the Bavarian club and he has already been linked with a move to Bundesliga rivals Wolfsburg.
The arrival of Luiz Gustavo from Hoffenheim puts his place in the Bayern midfield under threat and he admitted before leaving with his club for a winter training camp in Doha on Sunday that he is open to offers.
"I cannot say for definite that I will be staying at Bayern,'' he said. "The transfer window is open until January 31 and we will just have to wait and see. My phone will be switched on while I am in Qatar.''
At the same time, Van Bommel denied that the signing of Luiz Gustavo had prompted him to consider his future.
"I am very happy that he is coming,'' said the Dutchman. "We have got to welcome anybody who strengthens the squad and help them settle in as quickly as possible. That helps the team and the club.''
Bayern will train in Qatar for the next seven days before returning to Germany in preparation for their first Bundesliga match of 2011 at Wolfsburg on January 15.
