I don’t agree about Negelsman, he is an excellent coach and there was no good reason for his dismissal, just after a short series of draws, something incomprehensible began. Perhaps they also wanted to fire him for some other reasons, and this became only an excuse, then in this case he has no chance of returning to the team. I don’t know why everyone is talking about Zidane, if you look at his attitude towards his coaching career, I have the impression that he is not interested in a coaching career at all.
Nagelsmann did a really good job in his first season. I must admit that. He won the Bundesliga title by really decent statistics. However in his second season they had serious difficulties in repeating this success. You would remember how Dortmund got ahead and how much they got close to winning the title as well. This was the reason why the board wanted to part ways with him.
Bayern Munich officials are prioritizing Bundesliga title a lot to keep their manager or not. If Nagelsmann won the Champions League title then I assume the board would continue with him anyway.
He isn't a bad manager in short but he had a really big responsibility there which he couldn't maintain.
