Stop looking for a scapegoat and focus on building the club for next season, that is a wiser step for Bayern in response to their failure this season. Overall, Bayern is even performing better than last season, where they are now able to collect 72 points, and have the potential to get an additional 3 points in the next match. So it is clear that Tuchel succeeded in bringing Bayern beyond their achievements last season, only they failed to win a trophy because Leverkusen was never defeated.
Besides that, Bayern failure does not come from Kane curse, I don't believe in curses, Kane has even helped Bayern with a number of goals he has scored this season. I think this is purely because Bayern is unable to create consistency like Leverkusen, who have never been beaten in all matches.
Bayern Munich is the most successful German club in the history of the game of football and I strongly believe that they'll bounce back to their position immediately another manager takes over the managerial position at the club. Thomas Tuchel helped Chelsea win the UEFA Champions League title three seasons ago but after that particular season, he's not been convincing again with his performances. Hopefully, he gets another coaching job from one of the top European clubs
