For top clubs, to some extent, the main requirement for a coach is that he does not spoil anything in the first place. It is difficult to expect (with such a composition and dominance as, for example, Bayern) a result in the national championship other than the title. The figure of the coach is not very important here. On the other hand, in the Champions League there are no guarantees even for the top team and top coach (for example, City and the paper best coach Guardiola). Therefore, if we think logically, there is nothing wrong with hiring a young coach (who has already proven himself).
With the players he currently has, Xabi Alonso is able to bring Laverkusen consistently in two competitions, especially if he coaches a club like Real Madrid or Bayern Munchen he will definitely be successful with various trophies. However, it seems that Xabi will find it difficult to refuse if he gets an offer to train from these two clubs, even though his contract will end in June 2026. Only a very few players are successful when changing their role to become a coach, in the sense that he is equally good in both roles, Xabi is able to balance it very well.
It is reported that Xabi release clause is quite large, namely around 18 million Euros, that is a fairly large figure for a coach, but for clubs like Madrid, Bayern and Liverpool who are reportedly interested in him, it is not difficult to come up with a figure of that amount. However, so far there has been no official news about where Xabi future is heading, even though we know that Madrid needs a new manager at the end of the season and it is rumored that Xabi will be approaching the Santiago Bernabeu.
This is an insignificant amount given the general state of affairs on the market, plus I don’t think that if Xabi agrees to move to Real Madrid, this entire amount will be paid, most likely Real will “peacefully” agree with Bayer on less compensation.
Considering how poorly things are going for the Brazilian national team (yesterday they suffered a second defeat in a row), the need for changes there is obvious and the first candidate, according to rumors, is Ancelotti. I think Real are already preparing the transfer of Xabi, behind the scenes for now.
