Despite Kompany is not an experienced manager so far, I have a little confidence that he will do well because he has quality players at his side currently in bayern Munich. Many people are judging Kompany only based on his last performance in the Premier League and how Burnley was relegated, but many have forgotten that he was the manager who promoted them to the Premier League. The truth about why Burnley was relegated is that they did not give Kompany enough funds to strengthen the squad after they were promoted to the Premier League.
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.
But regardless of how it is, I don't underestimate Kompany. It is not to promote a team to Premier League competition, but all we are saying is that Bayern Munich is a big team with experienced players.
