I understand what you are talking about. For me, there is nothing wrong with Xabi Alonso coaching Bayern Munich next season because Bayern Munich and Bayern Leverkusen are not on the same level. Xabi Alonso's good performance at Bayern Leverkusen is for him to get a bigger contract from big clubs, which is already working out for him.
That's right, it was legal when Xabi took over the coaching chair of Bayern Munich, because Bayern Munich is also one of the teams that can compete in bigger competitions, such as the Champions League. However, if Xabi thinks the same thing as me, then he can stay at Leverkusen, because Leverkusen itself is certain to get a place in the Champions League next season. That way he can show that he is a coach who can really compete, he has to prove that because so far many people have said that this is Xabi's luck.
However, if he wants to leave, that's not a problem either, because this is also an opportunity for him to be in a bigger team considering that there are so many teams who want to work with him next season. Names like Liverpool also appeared, because Liverpool itself was certain to be abandoned by Jurgen Klopp who chose to resign, even though Liverpool still really needed him. So Xabi can take the opportunity to manage a team in a more prestigious league.
If Alonso leads Bayern Munich, the relationship with Leverkusen will be affected more or less. In particular, Bayern Munich is a direct competitor for the Bundesliga championship with them this season. Alonso is a strict and very disciplined strategist. Therefore, he cannot let speculation about the future affect Bayer Leverkusen. Alonso has carefully refused to speak to the media when talking about the future or other negotiations. Simply put, every rumor we read is just a hypothesis. It is likely that coach Xabi Alonso will stay at Bayer Leverkusen for another season. Leverkusen's board of directors wants to keep him, and Alonso also seriously considers the possibility of continuing to stick with Bayer Leverkusen. Indeed, next year, Xabi Alonso and Bayer Leverkusen will perform impressively in the Champions League. This is also an opportunity for him to prove his value more.
I want to see Xabi Alonso lead Real Madrid in 2026, thereby becoming Carlo Ancelotti's successor, because that time coincides with the expiration of his contract with Leverkusen. Real Madrid will really help him reach the peak of his career.
