I'm not sure about this but I think the good thing for Kompany and Bayern Munich is none expect to see a good performance from Kompany because he had a bad experience in the last season and he is still young and not experienced enough and this can make Kompany be under less pressure while on other hand, he is working in a team like Bayern Munich where they usually win the Bundesliga title otherwise they get the coach fired.
I think now Bayern Munich feels regret because of getting their coach fired and hiring Tuchel in the last season. Because this made the team unstable.
If I should judge Kompany based on his career records, he is not a bad coach. At the same time, he is not a good coach, so from my perspective, I view him as an average coach. Honestly, I was surprised that Bayern Munich chose Kompany as head coach because, based on his record, I don't believe he deserves the position he holds at Bayern Munich now. I can't yet conclude on his performance at Bayern Munich, but I don't expect any great performances from the team under Kompany as coach.
I remember how Chelsea made mistakes by signing Lampard as head coach, and nothing good came of it. I just hope the case of Kompany does not turn out like Lampard's tenure at Chelsea. In my view, Bayern Munich might be too big for someone like Kompany to coach. However, he does have a good squad at his disposal, which could help him perform better.
Everyone was surprised to see Vincent Kompany joining Bayern because he was the Burnley boss. The thing is, on paper, Kompany seems like an average manager, and calling him average won’t be anyone’s fault, as he doesn’t have anything that he won to show for it to be called a good manager.
But football is way beyond trophies and wins, and I think that was the main reason why Bayern went for Kompany. He has played a good amount of years at City and knows the game inside out. He has Pep’s doctrine inside him, and his footballing philosophy and tactics are much similar to Guardiola's as well.
Bayern went for a young energetic manager as this current era of football is seeing a lot of shifts to young coaches. This might be beneficial, or this might backfire too. Who knows?
