Wondering how Dortmund is going to perform in the next season because they had their own policy to sell the players for years that's how they usually earn money. This business helped them to earn money by selling players like Haaland to Manchester City and now other players Jude Bellingham to Real Madrid while we know if Dortmund had both players in this season, by using a player like Haaland they could have much more chance to achieve the Bundesliga title, but they prefer to earn more money instead of this.
I don't think there is matter of worry about Borussia Dortmund future because mostly they make their way for the having better results into Bundesliga which is their trading, and they never try to won trophies because this is not in their target now they already sold their best player for this season Jude Bellingham to Real Madrid which bring good profit for them and now their agents are working on for having few youngster which will do good work for them in this season, and they will be able to have youngster in their squad which will helps them for development and then have again huge profit.
Lewandowski, Haaland and now Bellingham all are bought for this purpose with now having their life impressive into their dream clubs, hopefully things will be gone as like this for them, and they will collect huge funds with this way as well.
It is true that Borussia Dortmund has shown they can compete in the Bundesliga and achieve successful results but it would be premature to dismiss any worries about their future. While it is true that they place a premium on dependable performances in their home league, saying they never pursue trophies may overlook their desire to succeed in a variety of contexts. While the sale of Jude Bellingham to Real Madrid did result in a sizable profit for Dortmund it is crucial to keep in mind that the club has a history of identifying young talent and developing them into excellent players. Lewandowski Haaland and Bellingham are examples of the kind of talent they have acquired as part of their strategy allowing them to grow and when the time is perfect produce significant profits. However it is important to recognise that sport is unpredictable and a thorough assessment of Dortmund future prospects necessitates taking into account several aspects other than player moves such as management decisions financial stability and league competitiveness.
