I read how Oliver Kahn commented on this dismissal, he said that they hoped for a long collaboration with Negelsman, but the results after the break at the World Championships became unsatisfactory.
Perhaps this makes sense, because Bayern have a recession in the game and they decided not to wait for the moment when things get even worse. Tuchel is a good coach, I knew that he would not be left without a team for a long time, but I think that no one could have predicted such a development of events with the dismissal of Negelsmann, and that Tuchel would be the head coach of Bayern.
Even though i did not think that Bayern would fire Nagelsmann so early, because the have paid a very big transfer fee for him, i have to say that i can totally understand that the Bayern officials were very unhappy with the performance of the team in the last few months in the Bundesliga. In the Champions League team every players is motivated anyway so the matches in the Bundesliga are really ones that show if a coach is still able to motivate his team and to be honest it seems like Nagelsmann was not able to do that anymore. If a club is able to beat Paris Saint Germain two times, then the same team should definitely be able to also win against Köln, Gladbach and Frankfurt.
