I don't think hiring Thomas Tuchel was the right move from Bayern. He may have experience but I don't think he's the kind of manager that they like. Bayern struggled after Tuchel took over. While that may be because he's just coming, it may also be because he's not capable of the task. The fact that a manager is experienced doesn't mean he will be successful at any club he goes.
Based on the reinforcements that Bayern are trying to get this summer, they may win the league easily but they won't get to the semi final fof the champions league. There will be no real difference between Nagelsmann's Bayern Munich and Tuchel's
Negative sentiment has also been reported coming from several circles of Munich fans after Tuchel's arrival. because in fact, Tuchel was not very successful in forming the Chelsea team before. it's the whole performance, not because of Tuchel and Chelsea in the Champions League.
but we'll have to see how Tuchel will shape his squad in this summer's transfer window. if Tuchel has good players in his squad, maybe Munich can talk a lot in the Champions League. depending on which will be the priority.
