I consider Kompany as a very lucky man for finding a big team like Bayern Munich in an double awkward situations. First they lost their Bundesliga title, second they don't have a coach and basically no one of the top coaches wants to train them.
I believe this experience will whether make him famous or destroy his career and might not be able to find a first league team to manage.
For Bayern Munich, they will try him and if results don't follow, they will sack him and try to persuade Klopp? Zidane? Mourinho? to join them.
