It seems that Bayern Munich's decision to fire Julian Nagelsmann seemed very hasty without technical considerations, he managed to achieve positive results in the Champions League with 8 wins from 8 matches and an extraordinary achievement for the Bayern Munich team, especially against big teams like Barcelona, Inter and PSG at 16th round.
However, on the one hand, Bayern Munich's management was not very happy with Bayern's achievements in the Bundesliga after being 1 point adrift from Dortmund in the standings. Maybe this was a strong reason for the dismissal of Julian Nagelsmann, which shocked the public because of his extraordinary achievements in the Champions League.
