That is inseparable from the behavior of those who always make movements contrary to what Bundesliga fans expect. We are waiting for a move from Borussia Dortmund that can improve their performance to break the dominance that has been held by Bayern Munich for a very long time.
I personally have always been disappointed with the movement of Dortmund from year to year.
To be honest i personally think that the difference in terms of the quality of the player squads between Bayern Munich and Borussia Dortmund has probably never been higher in the last 10 years or so then it is in this season. I mean yes, Dortmund made some good transfers with Süle which came from Bayern and also Schlotterbeck. Both of them are very good defenders and should help Dortmund to become more stable in the defense.
Bayern Munich has signed Mane and De Ligt though, those are not just very good players, those are absolute world class players. If i look at the starting eleven of Borussia Dortmund then i only see 1 player with Bellingham that may also be a starting player at Bayern Munich, all the other players are good, but not top level.
