What about Kompany, if I compare with Arne Slot then Arne Slot should be better. So he has better management skills. Feyenoord managed to finish in 2nd place in the Dutch League. While Kompany with Burnley failed to survive in the EPL. I think right now Kompany is also with Munich. With the big history champion in Lague and Europa. They both won the same club with good achievements so there is a heavy burden. When there is a new coach and does not have good statistics it looks bad, but I don't make statistics, statistics are just records sometimes there are always new surprises that can be bad or good.
I think this is something difficult, and I even disagree a little when comparing the performance of 2 coaches in different leagues. Although maybe in this case I also have a little doubt about Vincent Kompany because his performance with Burnley was not expected, Burnley had to be relegated this season under his coaching.
However, unlike Burnley, at Bayern Munich he has a very good composition of players, so maybe that will be the difference between his performance in his previous team and at Bayern Munich next season. I hope what I say is not much different from what happened. Vincent Kompany must be able to maximize the "luxury" squad he has.
I will not rush to conclude whether he deserves to be with Bayern Munich or not, I will give him the opportunity to prove that he deserves to be on the coaching bench of Bayern Munich with head status.
