I agree that Bayern Leverkusen should not be playing so seriously since they have beaten Bayern Munich for this season's Bundesliga title, but since they want to end this season unbeaten, they will be serious with every single match they play in the Bundesliga. Bayern Leverkusen needs to win or draw their last match in the Bundesliga this season to end the league unbeaten, and I believe Augsburg will not be a threat for Bayern Leverkusen.
Leverkusen will still play seriously in the last Bundesliga match, especially since their opponent is Augsburg. even though this team sometimes gives surprises, in the last 4 matches they have suffered consecutive defeats. In this match, considering that Leverkusen has a meeting against Atalanta in the Europa League Final, Xabi Alonso will not field his main line-up to save the energy of several of his core players. Even though they don't play their core starting eleven, that doesn't mean Leverkusen won't play seriously. After all, they have other player options that Alonso can rely on when hosting the match against Augsburg at BayArena.
The point is, maybe now the Leverkusen coach wants to record his unbeaten record throughout the season in the Bundesliga. In fact, perhaps Alonso has the ambition to continue this in various competitions, namely the Europa League Final and the DFB Pokal Final. After all, Leverkusen has a chance for that even though it has to be paid with effort and hard work to make it happen. and if he succeeds in bringing his squad undefeated in various competitions this season, it will be something extraordinary for this Spanish coach in his career with Leverkusen. To find out, we'll just see how far Alonso can go. They already have the Bundesliga, only two trophies are Leverkusen's current targets. well, very interesting.
