Veteran keeper Oliver Kahn said on Tuesday that he might hang his gloves if Bayern Munich won the Champions League. "It is likely for me to retire the game if we clinched the Champions League trophy this season," German media quoted Kahn as saying on national television. The 37-year-old international, who was the second-choice keeper of the German team that won the bronze medal in the World Cup earlier this year, said he wants to quit on top before people call on him to retire. Kahn will make way for Bayern's substitute shot-stopper Michael Rensing when Bayern play Alemannia Aachen in the German Cup on Wednesday. Coach Felix Magath told the club's website that he wants to give Kahn's long-term successor as competitive games as possible. "Rensing is Kahn's designated successor for us, so I believe he needs match practice when there's something at stake. I have complete faith in him," he said. During his 12-year career with the Bavarians, Kahn won seven league titles and one Champions League trophy. He led Germany to the final game of the World Cup 2002 before losing to Brazil. Though, he was named FIFA's best footballer of the tournament.
