Burnley is mediocre team but still, Vincent Kompany manage to guide then to become one of the fiercest mediocre EPL team, promoted them to English Premier League, but somehow they got demoted because they failed to meet the requirements. Perhaps Vincent Kompany found favour in the eyes of Bundesliga giant, he have more work to exercise in his new club, definitely going to be tough for him in the first season because there's more handling responsibilities to take of. The players in Bayern Munich are no mediocre players but experienced players that knows every corner to win games.
The squad differences are very significant between Burnley and Bayern Munich so that makes it a little easier for Vincent Kompany to handle Bayern and I don't think we can compare what happened before because Bayern management definitely has strong reasons so they recruited Vincent Kompany to be the team coach. , I think from the vision and mission of playing the team built by Vincent Kompany is suitable for Bayern and the players that Bayern has so that is a strong reason for Bayern management to appoint Vincent Kompany as their new coach.
