I think he must have gotten used to this situation a lot in his football career because Kompany is a player who has played with many world stars at Manchester City. He must know how to handle the star players at Bayern Munich because he has come from this business. The Bundesliga is a difficult league but Kompany will get used to it right away, he came here from the center of that difficulty, England.
For two league games Kompany has worked well. He got a maximum of 6 points. But I also see that Bayern Munich has not played against a strong Bundesliga team. Like Leipzig, Leverkusen. So the Kompany exam process has not been tested definitively. They will also feature in the UCL so let's see. It seems that he also wants to prove the doubts of his supporters. So far his winning record is still perfect.
At the beginning of this season, many people praised Vincent Kompany with the 6 points that Bayern Munich managed to get. I agree with @Luzin opinion that Munich has not yet found an equal opponent. So Vincent Kompany cannot be fully said to be a reliable coach when he has not passed the tough obstacles facing several other strong teams and competing in other competitions. In the next few weeks we will be able to see whether Vincent Kompany deserves to be called a great coach and can bring Munich to a higher level. Competing in several competitions is not an easy task even though he has experience as a Man City player.
