Perhaps the biggest problem is the financial situation and differences between Bayern Munich and other clubs. By having good management for years and years, they have a healthy bank account and can actually buy and sell whatever they want. Rarely do you see bad buys at Bayern. Almost all the players who have passed them have become very good. And if you have a sound financial policy that results in a high bank account, it is also easier to build in stability by attracting experienced and good players. Other clubs do not have that luxury and are therefore often left behind. Dortmund received a lot of money for Haaland, but what did they finally get for reinforcements?
Bayern Munich is surely one of the best business models in the sporting world with their sources and facilities which are giving them quality and consistency in their long run performance in the UEFA it's not happened in one or two years they have done good and long run planning then management able to have system like this right now we have no other club in Germany which can do things like these, but I check few details about clubs with this I have feeling Freiburg management is also doing things like these even this will take time, but surely they can do and this could be game changer for them in long run.
Borussia Dortmund is another club which had potential but things never been ideal for them because as they have big amounted they start journey for the new players and their team's moral never been on same level.
