Yep. We can say that Bayern became infected with instability from Dortmund. Last season, everyone laughed at Arsenal, Dortmund, United and some other teams that showed a very convincing game and then lost points out of the blue in the next game. Bayern got the same disease this season. In the next round they play against a clear outsider (even if it shows excellent results in the fight for survival), but even in such a game you cannot be sure that Bayern will win. In addition, the coefficient for the victory of Bavaria is simply ridiculous - 1.11
Bayern Munich have had a really bad performance this season, but there are several reasons. The most important and perhaps the first of these is undoubtedly Lewandowski's transfer to Barceona, followed by Neuer's unfortunate injury, and finally their firing of Nagelsmann before their crucial matches in the champions league and bundesliga. Some problems were not events under their control, but they created some problems themselves and opened the door to this critical process. Despite all this, I think they will be champions. Even when Borussia Dortmund took advantage last week, I predicted in that direction.
Lewandowski's problem would have to be solved in any case - due to his age, he began to play worse, and as we can see from his statistics in Barcelona (if I'm not mistaken in La Liga, he is in first place in terms of the number of unrealized scoring chances), he is not as good as he was earlier. The same can be said about Neuer - it's time to change him, and after the injury, I'm not at all sure that he will return to his previous level.
And here we come to the key problem of Bayern - they live in the past and do not want to pay a lot for top players. But given the existing realities, with many clubs willing to pay 100+ million for good players, Bayern have the choice to either stagnate or join the race. At the moment they have chosen stagnation.
