Goalkeeper Tim Wiese admits his future at Werder Bremen is uncertain amid speculation he could leave at the end of the season.
The 29-year-old, who joined the club in the summer of 2005, is under contract until June 2012 and if he was not to agree a new deal Bremen may have to look at selling at the end of the current campaign.
Wiese, a back-up to Manuel Neuer in the Germany squad, is not unhappy at Bremen, but he has also not given any assurances over his career.
He told Express regarding his future: "I simply just do not know. I am seven years with Werder Bremen at this point in time.
"I have played a lot in European Cup competitions, played three German Cup finals and like my job at the club. I am still open to everything.
"Bremen is a top club. We have been top of the Bundesliga at times. We played good matches in Europe. This is a good success."
