I see Leverkusen main mission is not to dominate the League but rather to pursue financial gain that's why they sell important players at high prices, Leverkusen is not the only team to do this in the Bundesliga we know Dortmund also did it a few years ago the difference is that Dortmund repeats the same pattern every season and actively looks for new talent while Leverkusen got new talents by accident. For next season I would not be surprised if Munich dominates the league again because that is their main focus while their finances are always stable so Munich will not use the same method as Dortmund and Leverkusen.
