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 don't want to draw conclusions too quickly about Kompany, even though Nagelsmann and Tuchel are actually much better than Kompany from experience, of course Kompany is very far below both of them, but it is true that there is no other way for Munich to get a new head coach who is suitable for Munich next season. , they feel confident and believe in Kompany so in my opinion as a Munich supporter we have to admit their decision of course it could be the best decision for Munich, at least Munich has solid and quite productive players which is enough for Kompany to carry out his job as head coach of Munich the new one.
After all, if a great coach but doesn't have productive players the results won't be good even though we know Xabi Alonso can do it, but it all depends on the approach between the coach and all the players, I think Kompany will also work hard with the trust he received during his time as head coach, of course he won't disappoint Munich next season, the competition is quite tight, he and Kane hopefully can get their dream next season with Munich, I hope Kane doesn't fail again to bring Munich a trophy next season.
