Yes, Dortmund does need rich owners. Because without some rich guy owning Dortmund right now, they are not going to improve. The moment they will show some improvement, the club is going to sell the players that are actually playing well just for profit.
And that is something that has been going on for quite a long time right now in Dortmund. This has to change, otherwise, they are not going to be recognized as a competitive team in the Bundesliga. Which is almost the case right now.
Dortmund have made a lot of profit from selling their players. that is why until now, Dortmund is unshakeable. they do not need a rich owner, like the billionaires who come from Arabia. Dortmund has done a very good business, and we can see that there are many Dortmund players who have become stars. in this winter transfer window season or next summer transfer window, Dortmund will reap huge profits if their two players namely Jude Bellingam and Youssoufa Moukoko are released in the next transfer window and they will replace them with talented newcomers.
This is the business that Dortmund's management runs, because of that they don't rely too much on sponsors and selling match tickets. most importantly, Dortmund remains at the top level of the Bundesliga and always exists in the Champions League.
The thing is Dortmund is a very successful club when you think about the business that they are doing. Let me rephrase, they are not a very successful club when it comes to achievement. But they are a successful club when it comes to earning money.
Because they bring a player forward who is not relatively known. And they make him a really good player who can certainly attract some really big clubs. In the end, they sell him for a huge profit. Thats what has been happening in Dortmund for a long time. So, they have two options. They can continue making money by doing what they are doing. Or they can change the way and actually go for achievements.
