If in ligue 1 there is monaco, of course in the bundesliga there is dortmund who continue to sell their best players every year to other clubs, this is why so far it is very difficult for dortmund to be able to break the dominance of bayern munchen in the bundesliga, because every year they continue to fail to retain the best players there is, this season haalaand is one of the most influential players in dortmund and if haalaand goes to another club of course it is certain that dortmund will experience a slump in the remaining matches of this season.
oh, it turns out that is one of the reasons why Dortmund is always good at the beginning of the season and suffers a decline in performance in the middle of the season.
if you look at the situation, is Dortmund experiencing financial problems at the club? if this situation continues to be run by Dortmund, maybe they are just a place to develop players. but never tasted the advantage to enjoy the sweet treats of a good player from Dortmund.
So far I don't see if Dortmund have any financial problems, but they can't keep their star players, for example, let's see a few seasons ago, how easy it was for Dortmund to let a great player like Matt Hummels, Mario Gotze and Lewandowski, dortmund indeed did get a lot of money in terms of transfers but didn't that make Bayern Munich stronger, this season Haalaand also began to be often rumored to be bought by Bayern Munich and if that happened Of course the duo Lewandowski and Haaland would have had very danger in the Bundesliga.
Dortmund made a lot of money with the transfer of players like Dembele to Barcelona or Sancho to Manchester United so they should be doing pretty well financially. The good thing is that the Dortmund officials are acting very cautiously and don't just throw around their money like they do at Real Madrid (900 Million € debts) and Barcelona (1,35 Billion € debts) but that is not the reason why they always lose their best players to other clubs. The reason is that they are simply not a Tier 1 club in europe, so their best players always want to leave the club to go to Bayern Munich, the top english clubs or to Real or Barca.
