What is certain there is that they are good at finding young seeds there and making their young players potential which is always brought in by other clubs at a higher price.
There are so many names that they are selling for quite a high price like Haaland, Sancho, Pulisic and even Dembele being some of the players they have managed well, so even if they don't win the title they have a huge profit from the sales of their players.
Winning as a champion is just a bonus for Dortmund, on the last season they are near to making their move if only Erling Haaland stayed healthy I think Dortmund can have a chance of having truly a competitive game against Bayern Munich, but as you have said it is not their interest in getting that from Bayern and the other teams, if they have players that will prove unique, and has talent then it is a big win for them aswell if they can sell those good condition players
This season he was very fragile and did not perform optimally in undergoing the season there.
In fact, several times he only saw his teammates on the side of the field when they lost the match.
The problem of competition is indeed a little more difficult if they really intend to do that with Haaland's condition.
Now that Haaland has left there are several players who have considerable potential to shine again such as Giovanni Reyna, Youssoufa Moukoko and Bellingham who now seem to be new targets to become other shining players.
