I think Bayern Munich may not try to move forward with Tuchel again. Tuchel is an important coach, I definitely believe that. He also has very important successes, but this year's failure for Bayern Munich is enough for me to believe that he will not be in the team next year. Bayern lost the league for the first time in years and Tuchel is seen as the main responsible for this.
I don't think this is entirely Tuchel's fault. In previous seasons, Munich had also lost several times in the Bundesliga. But because other teams played worse, Munich could become league champions. This season Munich has 7 defeats and last season they had 5 defeats. That's not a big difference. You can see that Munich's achievements this season are not much different from last season. But Leverkusen's extraordinary performance managed to beat Munich and make them lose the title for the first time in many years. Yes this is Tuchel's fault but I think it is the fault of the team as a whole.
