Kahn has been in good form this season, and could extend his stay beyond 2008.
Karl-Heinz Rummenigge told Bild: “He has a contract until 2008, but I believe we have not reached the end of the road with him yet.
“That is for Oliver himself to decide. Perhaps he will come to us in December. If he wants, then we will talk.”
Bayern coach Ottmar Hitzfeld defended Kahn’s blunder that gifted Markus Rosenberg an goal at the Allianz Arena in the weekend.
Hitzfeld said: “The goal could have been avoided, sometimes you wish he came out a little more. But against Real Madrid he saved us from going out.”
