Have Bayern Munich blown it? Replacing Julian Nagelsmann with Thomas Tuchel could be one of the worst managerial changes in Bundesliga history

Less than a month after suddenly replacing Julien Nagelsmann as Bayern Munich boss, Thomas Tuchel was fielding questions about a club in crisis. "I can absolutely understand that three years without a semi-final in the DFB-Pokal is not enough," he told reporters on April 21. "But the quarter-finals of the Champions League three years in a row is not a crisis.

"We don't have to question everything. There's always a sense of being realistic. Many big clubs didn't even make it to the quarter-finals. Although we remain ambitious and we always want more, we're still first in the Bundesliga. I wouldn't say we're in a crisis."

They definitely are now, though. On Saturday, Borussia Dortmund will end Bayern Munich's run of 10 consecutive German titles if they beat Mainz at home. It would be a stunning achievement by BVB, but an utter embarrassment for Bayern, who are operating on a whole other financial plane to everyone else in the league.

Heads would almost certainly roll at the Allianz Arena, with sporting director Hasan Salihamidzic and CEO Oliver Kahn already under intense pressure over what is now looking like one of the most catastrophic calls in German football history.
