Of course Real Madrid prefers to extend the contract with Carlo Ancloti because they feel his coaching style is suitable and by extending Real Madrid there is no need to adapt again to a new coach, after all Real Madrid has become an important part of Carlo Ancloti because this coach prefers to extend his contract and refuses coaching the Brazilian national team. Xabi Alonso is a good coach but because Xabi Alonso does not have as much experience as Carlo Ancloti, Real Madrid prefers to keep their coach.
Yes, Xabi current weakness is that he cannot bring Leverkusen to the title, but if Xabi Alonso is able to bring Leverkusen to the title. Xabi will show that his talent is like that of an experienced coach, but in my opinion, Xabi is a very good coach because even though he is still young, his coaching style following developments and making Leverkusen a team that is currently feared like Bayern Munich.
I can understand why they would prefer something like that, but they also need to act quicker if they want to get someone as good as Xabi. I mean 2026 is not that much further down the line but also quite a long time. Anyone who thinks that Xabi would still be managing Leverkusen in 2026-2027 season must be kidding, he is good enough that if he finishes this season like this, would mean that the entire world would be watching him next season, trying to get him maybe even during the season itself.
Look at United for example, do they not have the money for it? Of course they have the money for it so they could do anything, and for that to make sense, we are talking about a situation where Xabi may get the job during the season next season. Real has done something risky with this move, great for them on short term, but not great for long term.
