indeed this is just a temporary rumor but it could happen in the next season but what is certain is that Xabi wants to stay until Leverkusen is able to get the title he wants so that when Xabi goes to Real Madrid Leverkusen will have success without feeling disappointed when the coach leaves him because Leverkusen can be as strong as this because they received support from Xabi and got the right strategy, even Leverkusen was almost able to break dominance of this bundesliga giant thanks to Xabi, who currently has very good intelligence.
of course, before losing this best coach, Leverkusen will look for new coach early before Xabi leaves and I am still a little unsure Leverkusen will let Xabi go because in several seasons Xabi has been the best coach.
I doubt that there is such a thing as a superordinate agenda where people genuinely care in the football business that the clubs or players they leave behind can look forward to a safe and successful future. I would like you to be right, but this is too much of a utopian, hardcore business driven football world where it is all about making cash. If Alonso gets an offer and Real Madrid wants him and is willing to pay a fee to get him released, your scenario will collapse like a house of cards. I wonder if Alonso's contract, which expires in 2026, allows him to leave the club considering specified requirements.
