I wonder whether Dortmund will go for some new players in the approaching transfer window. I would really love to see them strengthening their defense more. Because I think that their biggest problem is with their defense. This problem causes them to make so many simple point losses which leads the gap with Bayern Munich to increase a great deal. But I feel like Dortmund won't go for a change now and will do their best with the current lineup. And they won't probably be able to do anything against Bayern Munich's reaching another championship.
This season is lost anyway. They should now try to consolidate, secure the 2nd spot, maybe have a small chance in the cups and focus on improve the team for the coming year
Dortmund needs to look for a replacement for Haaland because it is very likely that Raiola will find him a new club this winter. Of course one should not forget about the defense because indeed in Dortmund there have been quite big problems with it lately.
