I think the ability of Dortmund to compete for the title this season is still the merit of Bayern. The gap from third place is only 5 points (as in the last season). Therefore, we can assume that Dortmund on average plays the same as last year, and Bayern play worse. Therefore, the dissatisfaction of the Bavarian fans is quite understandable - they see that the team has become weaker and they do not like it.
Bayern's mistake was that they didn't use the transfer market very wisely, in the end, they bought the wrong player (Sadio Mane didn't play according to Bayern's expectations), if only at that time they bought Haaland or tried hard to keep Lewandowski in the team then Bayern's achievements would not be as bad as now This. only 1 point difference from Bayern, the opportunity for Dortmund to shift Bayern from the top is still wide open.
The bosses of Bavaria live in the past. They think it's still possible to get top players just because of their brand or cheap. But it doesn't work like that anymore. Even a free player demands a signing bonus simply for the fact that he chooses your club. Even a player who was already in Bayern, Lewandowski, wanted a more solid contract than for a year, and in the end, due to the fact that Bayern did not accept this desire, everything ended in a scandal. The bosses of Bavaria do not understand the reality they are already in. It will cost them dearly.
