I wouldn't say Leverkusen's performance as a team that won the Bundesliga trophy last season is mediocre at the moment. They are still playing well, it's just that their performance is not as good as last season. If Xabi Alonso gets the players he wants in the transfer market later, maybe he will fix his shortcomings this season. Although they are behind Munich in points, they still maintain their position in the standings well. Their chances for the Bundesliga trophy may be getting smaller, but they still have other competitions that they can try. So does Munich.
Leverkusen played great last season with the help of Xabi Alonso. We were all very surprised to see such a great performance of Leverkusen. We considered Leverkusen as a mediocre team. But Leverkusen was very strong last season. Leverkusen did not lose a single match in the Bundesliga throughout the season. Leverkusen won the Bundesliga title unbeaten.
Since Leverkusen did not lose a single match last season, we thought that Leverkusen would compete hard for the title this season as well. But Leverkusen's performance was a bit erratic at the beginning of this season. Because of this, Leverkusen has fallen behind in the title race. Leverkusen is still 7 points behind Bayern Munich. At the moment, Leverkusen's performance is stable. However, Leverkusen will probably not be able to compete for the title.
