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.
Agreed about this because if we check their history of last decade they have done too many things which bring good profit instead of having trophies which are also good, but everyone is going with his own mindset and Borussia Dortmund management is having this mindset for long time with a very long list of quality players those were sold just for money on crucial points because if they go for the title then surely this was possible, but they never try for this and have good profit from their strategy.
Now in this season they are having terrible time because after selling Haaland they have another good player but due to injury he is away from game for long period now things looking good for Bellingham as Liverpool and Real Madrid both are looking for this new wonder kid and this could be another big opportunity for the Borussia Dortmund having big profit.
