I also think Borussia Dortmund will not change their style easily. They have a team strategy that has been going on for years. This team strategy will continue. If they win the Bundesliga championship one day, these criticisms will gradually end. The Bundesliga is a league that is used to Bayern Munich winning the championship, but last year Leverkusen managed to destroy that. I hope this year will be a good year for Borussia Dortmund too.
One thing we need to understand is that not all clubs will be able to keep their most important players at the same time, some clubs are definitely just going to be developing talents and then letting them leave, clubs like Benfica and Ajax can also be good player’s example again. This clubs are built the same and no matter how they do well in their league they will end up selling their players, Dortmund isn’t different from them, even if they win the Bundesliga today they will sell off their best player to their direct opponents self, I could remember the same issue with the Lewandowski then when he moved to Bayern Munich.
