I believe that Xabi would be definitely perfect situation, I mean he still has age on his side and that means we are going to end up with him being able to manage that team for as long as possible.
I know that it is not going to end up with anything that crazy, like Xabi being their manager for 20 years, which his age means he technically could but we all know that won't happen, nobody ever managed a team for 20 years in that size teams aside from maybe Alex Ferguson, but I think he could do at least 5-6 seasons easily, that is a good thing for Real, maybe even as high as 10 years which would make him a legend at the club, and if he does bring in some success, like 50%+ la liga titles on his seasons, and a few UCL cups as well, then it would be lovely to keep him.
Real Madrid is a club that's known for their intimidating records of success when it comes to European football and have been able to hire the best managers to take care of the first team of the club over the years but their current manager Carlo Ancelotti who has also won the UEFA champions league with them will be leaving at the end of the season and that has raised concerns over who's experienced or capacitated enough to replace him at Real Madrid.
To many, they believe that Bayer Leverkusen manager Xabi Alonso is the best man that'll replace Ancelotti when he leaves the club next summer. Considering the impressive performance of Xabi Alonso this summer and the fact that he's a former Real Madrid footballer, I don't think there's anything that's gonna stop Real Madrid from bringing the Spanish manager to the Santiago Bernabeu next summer.
There is no doubt about this all but still things are not clear about this all because as we are having Bayer Leverkusen giving their best too much talk about Xabi Alonso and his future at this club is topic of the town but most chances we can't go as things are currently showing with most chances Xabi Alonso is having contract until 2026 with release clause for three clubs but as he is doing things here most chances he will not go quickly because this is also his start, and he needs to be more realistic for having impressive future and also if he is going to have more trophies than surely he needs to stay here which will increase his experience and value as well.
Carlos Ancelotti is also doing impressive job with his contract is going to end after end of this season and most chances he will leave for the Brazil but until now nothing is sure with few rumours are surrounding, he will extend his tenure here and try to stay until 2026 which could be also good for all parties.
