In the world of football, clubs like Dortmund and Ajax are well known for generating young players with high potential. The Dortmund authority is not interested in winning trophies, they only want money, and in order to achieve their objectives, they just produce young players every season and sell them to the elite clubs of Europe for bags of cash.
Besides Lewandowski, Haaland, and now Bellingham, there are also several other players on Real Madrid's radar and I don't think Jude would be able to resist an offer from Real Madrid if he were given one. The best way I can describe Dortmund's team is to imagine what it would have looked like if they had not sold any of their players!!

They got unknown young stars and turned them into star players before selling them off to the highest bidder. The real heroes in such clubs are talent scouts. The day the scouting team is gone, that's when hell breaks loose for the Club.
