I still can't believe that Bayern decided to sign Kompany. I think he is a great guy as a person, but I doubt that he is the level of coach that Bayern was looking for. When you look at their lost of coaches in the last 15 years, so many big names like Ancelotti and Guardiola and Heynckes, and then they got coaches like Kovac and Kompany. The gap that can instantly be seen between those coaches is so huge that Kovac and Kompany must have been moves by the club that came out of desperation.
Kompany has proven that he is capable to handle Bayern Munich. I don't understand that you are still trying to compare him with previous managers. I think it is not a must to have a big name, it is all about the capability to handle Bayern Munich. Before Kompany came, Tuchel is the coach and he is a popular manager. In fact, Tuchel failed to handle Bayern Munich. Under Kompany management, Bayern Munich dominated again the domestic competition at least. And Bayern Munich will has a chance to play in the final round of UCL if they can beat Inter Milan. Dude, you must respect him, right? It is his first season in Bayern Munich.
It is not a must because you have to get started somewhere like everyone. He has been getting away with a couple of things now because the other teams in the Bundesliga suck. Losing against Mainz and Bochum after leading, going through the playoffs and then get lucky against Celtic to not have to go through overtime and penalties. Luck was with him all the time. I am sure you don't try to convince me that Bayern is dominating the domestic league.
Many of the coaches could be recognized when they were coaching Bayern. Guardiola in particular, you could literally tell who Bayern's coach was without knowing beforehand it was Guardiola. With Kompany I don't know. Luck did its best so far. But I might be wrong and it is time for them to play against the strong teams like Barcelona to prove how good they really are. If they play against Barcelona like they played against Celtic, they are instantly out of the CL.
