Vincent Kompany has indeed gained great experience in the past but it is not a guarantee that he can make a difference to Bayern Munich, while Alonso is more able to provide a guarantee of being able to win the Bundesliga title again because Vincent Kompany is also his first time managing the Bayern Munich club, whereas it takes a little time to adapt and be able to brought changes to Bayern Munich's performance.
It looks like next season Bayern Munich will have to accept bad luck again or maybe worse, lose the Bundesliga title again.
Bayern Munich is strong enough to deal with their current challenges and eventually hitting harder for trophies. Bayern Munich have nothing to worry about because they're elite team and will dive in for major titles next season. This season they missed out but it doesn't mean they will struggle. Give him a chance and stop the panic. I've this feeling about Vincent Kompany excelling in Bayern Munich next season. Remember he's young and promising coach, he also gained experience to capture the long picture for the club.
