What is called dominance, as demonstrated by Bayern Munich, is that they managed to maintain their existence for almost several consecutive seasons over a long period, and no other team in the Bundesliga was even able to dominate them. Dortmund doesn't have the ability to match Bayern Munich's capabilities because they always try to sell every player who develops at the club, so all they think about is business. For this season, I doubt Dortmund can compete with Bayern Munich because overall, there are no changes they have made.
Dortmund will only be in the top four next season, but there's little belief that Dortmund might finish second next season if other teams don't perform significantly better. Since there aren't many teams in the Bundesliga with the same strength as Bayern Munich, Dortmund could have a chance to finish second next season. However, teams like Leipzig and several others could pose serious obstacles for Dortmund and Bayern Munich next season.
