Yes, this season is certainly a very historic season for Bayer Leverkusen. Xabi Alonso was truly able to play his magical role, making Leverkusen's game very difficult to stop. I admit that their greatness this season is not due to mere coincidence but that they are truly able to appear united by setting a clear vision and mission.
Being able to win the Bundesliga title and possibly also winning the DFB Pokal and Europa League trophies again is certainly an extraordinary achievement, coupled with an unbeatable record that makes Leverkusen very perfect. But what are their chances next season? I still have high hopes for Die Werkself even though it won't be easy like this season because I also believe Bayern Munich, Dortmund and maybe Leipzig will also improve their teams for next season.
Xabi Alonso built this team with a process that was not that long and the results were quite impressive, there is no surprise about what happened this season for Leverkusen because they have quite good quality and consistency so that up to now they have managed to create an unbeaten record.
Xabi Alonso has decided to stay at Leverkusen until next season and thus I am quite confident that Xabi Alonso will be able to maintain Leverkusen's performance as he has done so far, regardless of whether it is better or worse, but of course next season's competition will be different. When other top Bundesliga teams improve to be even better, especially Bayern Munich, of course they will be ready to compete fiercely again for the Bundesliga title next season.
