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.
Leverkusen is basically following the path shown by dortmund. We know that Dortmund has found a lot of talented players. And has been able to earn a lot of money by selling them. This team does not compete for the title in any season. At the same time , Leverkusen is also probably joining this group. They will now develop players and try to earn money by selling them.
Leverkusen has earned more than 200 million by selling players this season. They has sold important players like Wirtz, frimgpong, Kossounou and Xhaka. It is very difficult for Leverkusen to continue their good performance next season by selling all the important players in the squad.
Although Leverkusen has bought players like Quansha, Malik Tillman and Ibrahim Maza. But these three are young. Although they are talented, not much good performance can be expected from them.
