There is nothing wrong with doing business in the football industry and that is what they do to make a profit. If the business is run like the one run by the owner of Dortmund, they will never achieve the club's achievements. The reason is that they only focus on selling players and never try to buy quality players at high prices. A trophy is a big hope for any club, but if the club does not have a supporting force of quality players then it will be difficult for them to achieve it.
Obviously, These Football clubs are not just there for entertainment sake but are also for their business dealings and I do believe this is why Dortmund sold this incredible player at some point, fast forward back to when Arsene Wenger was in Arsenal as the head coach, this was a kind of business Arsenal football club was into, grooming of players and selling them when they are at their best to raise money for the club.
Are you aware, even though Dortmund always sells talented players, but in reality Dortmund is still capable and/or successful in becoming a team that can compete well in the title race every season. In fact, last season Dortmund almost won the Bundesliga title, but Dortmund again and again had bad luck in the last match of last season. So yes, even though Dortmund prioritizes business and profits, but the reality is that Dortmund still has very good management to remain a title-challenging team every season and that is of course great I guess.
The scouting team has become the main party who needs to be applaused here. it's not terzic who is not even helping the club to play even better. I hope that dortmund would be getting someone like jurgen klopp that can being dortmund to the its golden era again. Dortmund was not selling all of its talented players, but the club was doing it due to the financial stability that is needed by the club. People are not even aware about how much club's expenses.
Dortmund needs to keep its financial to be stable by selling more players to the another club. The fact that dortmund can still stay at the top 10. It must be blamed if dortmund played so badly like schalke after sold its players.
