Growing and developing the talents of the players so that they are really ready to be sold at a fairly good price, and then producing stars for other clubs. .......
Dortmund would have won multiple titles over the past few years if they had been able to keep the excellent players they have developed, but they claim they are in business because they are not a wealthy club and must sell the talented players they have developed.
And this has become an open secret, that's why, during the transfer season, active clubs in the market will usually also review Dortmund players. However, according to what @legendbtc said, fortunately despite this attitude, Dortmund remains one of the top clubs to date, both in the Bundesliga and in the big UCL competition. It's just that, they haven't been able to win the trophy. And even this season they started quite badly, their position in the Bundesliga was only number 7, losing to their competitors.
The Bundesliga will be more interesting if every season there is stronger competition for the championship title. But as seen in the temporary standings table, of course this season will be even more exciting because several teams are starting to show better performance such as Leipzig and Eintracht Frankfurt.
If we look at the number of points, the Bundesliga is much more competitive and interesting this season. Bayern Munich as the top standing also cannot be that calm, because the difference is only 5 points. while the next position, it is quite competitive with a small point difference and can change in 1 match result. Until position of Dortmund, it still has the chance to change again.
