Don't you realize that in every transfer window at the start of the season, Dortmund always sells its star players, but the fact is that Dortmund can always be Bayern Munich's toughest competitor in the Bundesliga. With that said, the departure of a key Dortmund player whether it's financially beneficial or not, I think it's still profitable for Dortmund because they've always done that. But one thing we have to remember is how much Dortmund has sold its key players, but Dortmund will also be able to compete in the race for the Bundesliga title.
How can you compete? Bayern Munich have won the Bundesliga 11 times in a row since 2013. From here it is very clear that Dortmund is a business club and prioritizes business and profit above all. It's different from the team in the EPL who can balance business and the quality of their team.
Dortmund seems to prefer to focus on business only and is not so ambitious in pursuing the Bundesliga trophy. Apart from the gap that occurred between Dortmund and Bayern Munich. On the other hand, Bayern Munich is too OP in the German league and it's difficult to just compete with them. This season, Dormunt was able to compete with Bayer Munchen and even almost won the championship, although in the end it failed, even that because Bayer Munchen was inconsistent again. this is the same as PSG in the French league. This dominance is too high, making clubs like Dortmund think realistically and prefer to stay in their comfort zone rather than having to compete tooth and nail against Bayern Munich's domination in the Bundesliga.
