This is will be too bad for dortmund if it is true, dortmund has always have the nature of selling their best players. They don't care to know if they need this players , them selling their best players is affecting their performance to win trophies.
If that's what they consider, it means that Dortmund doesn't really aim for trophies every season so they are still considering selling their best players to other teams when there are very tempting offers. The point is that Dortmund are only concerned with money for themselves without thinking about the careers of their players. Obviously this is very unfortunate because Dortmund should have kept the best players to win trophies, not just wanting to earn money from selling the best players.
Dortmund's goal was never to become champions of the Bundesliga. They just want to do business and make a lot of money by selling players. If Dortmund's goal was to win the title, they wouldn't have sold Haaland. They would keep Haaland in the team and try to strengthen their squad. But they don't do it. The main player of their squad this season is Sébastien Haller. I think the Dortmund management will make a lot of money by selling Sébastien Haller within the next two seasons.
This concerns their management which makes Borussia Dortmund always take actions like that. It makes perfect sense with what they are doing that Borussia Dortmund don't intend to win the title, but I don't see the same thing in other clubs, because other clubs are competing to win titles. This is very strange in my opinion. How can one club not want to be champions when they have everything it takes to make it happen.
I think if we want to see Borussia Dortmund win then we have to see a change in management first. It is very unfortunate for the players who are part of them when they have to become victims of the business they run.
