Rumors surrounding Niko Kovac's departure started circling on Sunday evening, only for the club to confirm that they'd agreed to a parting of the ways with a tweet that read simply: "FC Bayern parts ways with Niko Kovac."Saturday's heavy defeat to Eintracht Frankfurt, Bayern's heaviest for a decade, saw the champions slip to fourth in the table and the Croatian coach has paid the price."I think at this point in time it's the right decision for the club," said Kovac, who coached Frankfurt before Bayern. "The results and way we have been playing recently have brought me to this conclusion. My brother Robert and I thank FC Bayern for the last year and a half."The club confirmed assistant coach Hansi Flick, who returned to the club staff earlier this year, will take charge of the team for Wednesday's Champions League clash with Olympiacos and Saturday's crucial league match with Borussia Dortmund."The performance of our team in recent weeks and the results have shown us that there was need for action," said club CEO Karl-Heinz Rummenigge."Uli Hoeness [president], Hasan Salihamidzic [sporting director] and I have an open and serious conversation with Niko on Sunday with the consensual result that Niko is no longer coach of Bayern. We all regret this development. I would like to thank Niko Kovač on behalf of FC Bayern for his work, especially for winning the double this past season."After a difficult start to his tenure last term, Kovac went on to win the Bundesliga and the German Cup, though Bayern exited the Champions League to eventual winners Liverpool in the last 16.Bayern have won the last seven Bundesliga titles but have now had three coaches, including the temporary return of Jupp Heynckes in 2017-18, in the last three years. Kovac's reign of 490 days is longer than that of his permanent predecessor Carlo Ancelotti by 36 days.
