You just said Komapny is not an experienced player, and that is the reason why many are saying different things about the manager. People are judging him based on his last performance at Burnley; even though he promoted Burnley to the Premiership, they got relegated, and that is why many people are sceptical about him managing Bayern Munich. Although I know that Bayern Munich will have their own personal reasons for bringing him to the club as a coach, based on how people view it, people still think his experience is not enough to bring Bayern Munich back to their performance like before anytime soon.
One of the reasons why the club management chose Kompany was because Munich had no other choice. There were several coaches who were given contracts by Munich but unfortunately they did not accept them. I even read an article that said that they once offered a contract to Xabi Alonso, but Alonso chose to stay at Leverkusen. I'm not underestimating Kompany but tbh Kompany wasn't their first choice. Munich is a big club and many doubt Kompany's abilities. I think Kompany should be given the opportunity to prove that he deserves to be Munich manager.
It's not because they don't have a choice, but it is the desire of Bayern Munich's management to get a very professional coach, whereas professional coaches feel that if they accept an offer from Bayern Munich, they will have to bear the heavy burden of fixing the problems that have been left behind by Tuchel.
Kompany is not the only option, but there are still many better and more professional coaches to manage Bayern Munich's players to regain Bundesliga dominance.
At least this has become an option for this big club and we'll see what Kompany will do to restore all of Bayern Munich's strongest performance that has been lost before, even though I have doubts, I can still accept and give trust to the coach.
