Xavi Alonso has done great work at Bayern Leverkusen, not only by helping Bayern Leverkusen win this season's Bundesliga title but also by changing Bayern Leverkusen players's mentalities, and they will want to challenge for the Bundesliga title next season. I expect Bayern Leverkusen to still rival Bayern Munich for the Bundesliga title next season because they have seen the benefit of becoming champions and they will want to experience it again.
This season, Bayer Leverkusen still has the opportunity to win two trophies which are no less prestigious than the Bundesliga trophy. So next season, Bayer Leverkusen will have to be really wary of by every other team because Xavi Alonso will still coach the team and there is a possibility that it will continue to improve as it is now. I was also quite happy when I saw that Bayer Leverkusen was able to break the dominance of the Bundesliga giants this season so that this could possibly continue next season.
