In fact it was not bringing out the best players, but rather cashing in on the best players by selling them to other teams so that Dortmund's achievements could only come close to those of Bayern Munich. But it will not pass Bayern Munich as long as Dortmund still prefer to release their best players to other teams who then go back to print other players to be better. However, I prefer that next season Dortmund can compete better in order to win a trophy in the Bundesliga, because for the UCL trophy it seems that it is still a bit difficult for Dortmund to achieve.
Either Dortmund is playing better or Bayern is playing worse this season. So that their strength and their achievements are not much different. Even the decisive victory is in the last match. And Dortmund should have had such a big chance to become the title holder this season, but something went wrong and had to let Bayern win the trophy again. Dortmund really need excellent players, more than usual to continue to compete with Bayern and maybe excel. They certainly really want to end Bayern's dominance in the Bundesliga, but if their efforts are lacking, even in the selection of players, this will be difficult to do.
