Oliver Kahn says Bayern Munich's decision to replace Julian Nagelsmann with Thomas Tuchel as head coach was due to the team playing "less successfully and less attractively" since the World Cup.
The Bundesliga giants lost their lead at the top of the table at the weekend after a 2-1 defeat at Bayer Leverkusen, with Borussia Dortmund leapfrogging them with a 6-1 win over Koln.
Despite an impressive Champions League last-16 success against Paris Saint-Germain, Nagelsmann has paid the price for a dip in domestic form, with two of their three league defeats this season coming in their last five games.
"When we signed Julian Nagelsmann for FC Bayern in the summer of 2021, we were convinced we would work with him on a long-term basis, and that was the goal of all of us right up to the end," Bayern chief executive Kahn told the club's website.
"Julian shares our aspiration to play successful and attractive football. But now we have come to the conclusion that the quality in our squad – despite the Bundesliga title last year – has come to the fore less and less often. After the World Cup we have played less successfully and less attractively.
"The big fluctuations in performance have cast doubt on our goals for this season, but also our goals for the future. That is why we have acted now.
"Personally and on behalf of FC Bayern, I would like to thank Julian and his coaching team, and wish everyone the best of luck for the future."

Sporting director Hasan Salihamidzic echoed Kahn's words, saying it was "the most difficult decision in my time as a board member".
He added: "I have had an open, trusting, friendly relationship with Julian from day one. I regret the parting of the ways with Julian. But after a thorough analysis of the sporting development of our team, especially since January and with the experience of the second half of the previous season, we have now decided to release him.
"I am very grateful to Julian for what he has done for FC Bayern and I wish him all the best."
Bayern have appointed former Dortmund, PSG and Chelsea head coach Tuchel on a contract until June 2025.
