I'm not sure about this but I think the good thing for Kompany and Bayern Munich is none expect to see a good performance from Kompany because he had a bad experience in the last season and he is still young and not experienced enough and this can make Kompany be under less pressure while on other hand, he is working in a team like Bayern Munich where they usually win the Bundesliga title otherwise they get the coach fired.
I think now Bayern Munich feels regret because of getting their coach fired and hiring Tuchel in the last season. Because this made the team unstable.
Every team makes mistakes and the fact that Bayern Munich are not in good form now does not mean that mistake cannot be corrected. They must have done that in order to improve the quality of the team, unknown to them that this will be the case of the team now. Kompany is still part of the revival process they’re passing through to make the team good again. If he was not fit for the job or can tell if he’s the right choice for the club, they wouldn’t have employed him in the first place. Until the league begins, he remains the choice of Bayern Munich and will do everything to make the team successful.
The thing I didn't understand last season was how Tuchel managed that poorly.

I mean Bayern Munich had a wonderful squad, absolutely a complete one with adding Harry Kane also to the team.
Considering Tuchel isn't actually a bad manager, it was a really surprising thing to me. Their Bundesliga performance was horrible compared to the previous seasons. I don't know maybe he was going to fix things if he was given one more year but still...
I think this is normal in football and you can’t blame Tuchel for performing that poorly. When he joined the team, he won them a trophy in his first season and that was all overlooked because of just one season. Everyone could have their downtime and maybe that was his and he needed some cool off until the next season before he gets back to his real form. I have not seen anything that bad to warrant that sack. He made it to the champions league semifinals, that was something difficult to do and appreciable to anyone that did that. That was how he was sacked by Chelsea and till date, they’re still battling to get themself back in the league. I don’t hope for the same fate for Bayern Munich.
