When you make silly mistakes with several coaches and let them down and when they turned their back to you while you struggle to find an experienced coach then you have to take the risk with one of the rare ones that accepts to join you.
That's the whole story of Bayern Munich manager.
Bayern Munich is a team that has a lot of money so they can do whatever they want, including choosing a coach and also buying new players. But sometimes this does not guarantee that they can get good results in the League as happened last season, so next season Bayern Munich will also be handled by a new coach whose story may be very different from the previous coach. Because the first thing that Bayern Munich hopes for is good results and being able to become champions again in the Bundesliga.
