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.
In the last season because of Erling Haaland's injuries he has lost game appearance, and surely I know we can not blame it because that is an injury, but can we blame it aswell the whole team? I guess we can all assume they surely need to put more effort into making a new way if Haaland is not on the team, but I think they have a possibility to win against Bayern Munich when they still have Erling Halland, and right now their expected new Halland Sebastien Haller is not with them because of tumor cancer,
If a team's goal is to win the title, they should not be dependent on any particular player. They should definitely keep the replacement. It is impossible to guarantee that a player will play well for an entire season or suffer injury. The Dortmund team is not stable enough this season either. They may qualify for the Champions League, but will be far behind Bayern Munich in the Bundesliga.
