Bayern Munich were quite disappointing in the Champions League last season. Actually it has been the case for 3 seasons. They were the champions in the 2019/20 season. But since then their biggest success is to reach the quarter finals. In one of these seasons they were even eliminated by Villarreal surprisingly.
It looks like something needs to change really much for them to do better here. Tuchel might be the one to make this happen maybe. He was amazing by winning the Champions League with Chelsea in his first season already in a time that they weren't given much chance for this achievement.
Of course this was a really difficult task. But now Tuchel will have an even more powerful squad in his hands. It is all up to his managing to work his system with this team from now on.
That's why hired Thomas Tuchel, because of his experience in the champions league and they know a coach like Tuchel knows the way to make a team win the Champions League. On the other hand, Tuchel got a chance to have better teams than last season they are still hiring players like Kane for the next season which can increase their chances.
