Borussia Dortmund actually has great potential to be able to compete even more tightly with Bayern Munich. But yeah, I see they are not serious about it, they just want to have an advantage in terms of money for this team. The result as we see, they can not compete with the rulers of the Bundesliga, Bayern Munich. This makes the Bundesliga monotonous in terms of competition.
After making a profit from selling Haaland, this time Dortmund managed to get a pretty good defender, Nico Schlotterbeck. Dortmund's task this time is to find a replacement for Haaland, so they can continue to compete with Bayern. the gap (strength) between bayern and other bundesliga teams is very far and that makes the bundesliga a slightly boring league, much different from the premier league or Italian league.
