This has been a spectacular season for Xabi Alonso and Bayer 04 Leverkusen. Xabi succeeded in bringing his team to win two titles this season with an unbeaten record throughout the season. It is very difficult to beat them in the Bundesliga and other domestic competitions, even in the Europa League, but Xabi Alonso failed to perfect his achievements this season because he was defeated by Atalanta in the Europa League final.
Next season, Xabi's job in defending the title will be very difficult, of course because of the increased competition in the new season. The Champions League will not be easy for him, but Leverkusen is certainly considered a good team among many other contestants. I'm not sure Leverkusen can win the title next season in the Bundesliga, it's very difficult to defend.
Of course, Xabi Alonso has made a big contribution to Leverusen, because he has succeeded in making Leverkusen better this season and even very well by becoming a very different team because it underwent drastic changes which surprised many football fans. Even though they lost to Atalanta, of course it was detrimental to them, but I think the achievements of Leverkusen managed by Xabi Alonso are a very good achievement and should be appreciated. I think it surprised a lot of people with their failure against Atalanta because Atalanta was the first team to beat Leverkusen this season. I myself was surprised that Atalanta was able to beat Leverkusen.
With next season I think Xabi Alonso will do his best for his team. It is true that defending the title will be difficult because the competition will definitely get tougher in the new season. Also, with Leverkusen being a very good team at the moment, I think they will maintain it and become an even bigger team, but it will be a difficult journey for them.
Xabi Alonso has really changed everything about Bayern Leverkusen because they just came out abruptly without showing any sign that they will be this stronger this season because last season they finished 6th position just to come all of a sudden this season and made this huge difference, Xabi Alonso really did great job for Bayern Leverkusen. Even though he didn't win the Europa league trophy but that is not enough to condemn his efforts that he has put in developing Bayern Leverkusen to become stronger competitor in the Bundesliga.
I see no strong competitor for Bayern Leverkusen next season so they will still continue from where they stopped this season so if for any reason they drop in performance next season just know that it will be as a result of injury but if not no team can stop them not even Bayern Munich because Bayern Munich haven't been in their best performance and they look like they may not make any improvements, the only teams am seeing to contest with Leverkusen next season is Borussia Dortmund and Vfb Stuttgart.
