I agree that Nagelsmann is for sure better then Tuchel even Tuchel is also a very good Coach or he was.
I dont know much about Kompany but i think there was for sure better coaches on the market as him.
If Munich will be failing again that would be a shame for the whole club and the management and they should change there thinking.
The problem is that all the coaches who are better than him refused Bayern

I don’t know what will happen next season, but given the fact that Xabi remains, and Bayern does not look like a club that is going to seriously strengthen, there is a high probability that Bayern will fail again next season. Most of all in this situation I feel sorry for Kane, and the fact that the competition in the tournament is growing is only a plus.
I agree with you. Bayern Munich seems frustrated after several approaches to great coaches such as Roger Schmidt, Ralf Rangnick, Julian Nagelsmann, and most recently Xabi Alanso. However, all of these coaches flatly rejected Bayern Munich's invitation, causing Bayern Munich's management to reach a dead end and finally recruited Kompany as coach.
In my opinion, why Bayern Munich hired Kompany as coach was because Bayern Munich wanted to follow the example of Leverkusen who were successful in using young coaches, especially since both Xabi Alonso and Vincent Kompany were Pep Guardiola's students. Of course, this is a strong reason for Bayern Munich in making their decision. Yes, in the end we will all feel sorry for Kane, with a new coach of course it will take time to strengthen the team so it is certain that next season Kane will end the season without another trophy.
