That makes sense, Xabi Alonso will of course have big ambitions to improve the performance of the Leverkusen team next season, especially with the achievements they have achieved this season making it very possible for them to continue.
Meanwhile, Bayern Munich, with its new inexperienced coach, of course needs time to adapt and it is slightly beneficial for Leverkusen to be able to defend the title, but Bayern Munich still cannot be underestimated.
Because Xabi Alonso will be playing in the Champions League, of course he has to be able to build this team to be much stronger than last season, I think that's quite possible and regarding their unbeaten record they might maintain it, but that's in the Bundesliga, not in the Champions League.
Bayern Munich will remain a strong challenger to Leverkusen next season even though they do not have an experienced coach because in terms of experience Bayern Munich is a strong team with complete players in all positions. Leverkusen has the opportunity to retain the Bundesliga title as long as Xabi Alonso can maintain the quality of his players and not let the opportunity to play in the Champions League be an excuse for not playing consistently in the Bundesliga.
It's not easy to defend the title with the minimum number of players and last season's moments are difficult to repeat. Bayern Munich and Dortmund have new coaches so they have to be able to adapt beforehand so this is the best step for Leverkusen to maintain their title and play more solidly.
