Even before Dortmund sold Haaland it was a weak team (compared to the top ones), now it is obviously even weaker and I would not be surprised if they are moved from second place to third and maybe even fourth in the upcoming season. As for Bayern, they will not have any problems in the domestic championship, as for the Champions League, randomness is of great importance there, but they will definitely be in the group of favorites.
It's true, indeed if you look at Borussia Dortmund, they can even be said to be lucky to still be in the top 4 because their competitors are not better than Borussia Dortmund. If the position is like in other leagues in general, Borussia Dortmund is very threatened. And maybe they will be in the middle of the board. It's just that there is no better club in the Bundesliga.
