Former Germany boss Berti Vogts believes that Oliver Kahn should no longer be Bayern Munich's first choice goalkeeper.
The Bavarian giants have endured a frustrating season this term and given that the club are unlikely to qualify for next season's UEFA Champion's League, the ex-Scotland manager feels that radical changes must take place at the Allianz-Arena.
"If Ottmar Hitzfeld wants a fresh start, this must include anyone and he shouldn't shy away from touching the key figures unless he wants to risk his credibility," Vogts told Bild.
"I would send Oliver to the bench and give understudy Michael Rensing a chance to prove himself in the next game."
The 60-year-old has never been a big fan of Kahn, who was only second choice to Andreas Kopke when Vogts inspired Germany to success in Euro 96, and his comments could spark a debate about Kahn's future.
"Bayern need a blow of fresh air and Hitzfeld must find out if Rensing is good enough for the club," insisted Vogts, who was recently appointed as Nigeria coach.
Kahn, 37, has one year left on his contract with Bayern, but his status has suffered significantly since a number of private scandals appear to have affected his form and it was no surprise when he lost Germany's number one shirt to long-term rival Jens Lehmann prior to last year's World Cup.
Kahn has since retired from international football but has recently stressed that he is determined to fulfil his contract with Bayern until 2008.
