Unlike Ancelotti, I see that Alonso works with the players a bit differently. When Ancelotti was the coach, everyone noted that the atmosphere within the team was very friendly. Ancelotti tried to maintain very good relationships with each player. With Alonso, things are a bit different he tries to take a more professional approach, and it's already clear that he doesn't have the best relationship with Rodrygo. I believe the same is happening with some other players at Real Madrid whom he doesn't plan to work with. That's why I think this is also affecting the atmosphere within the team, and not in the best way.
Xabi Alonso knows what the club wants from him, and he really knows what he's dreaming of achieve. With those reasons, that's why he's taking the best steps. It's not that Alonso is not friendly with the players or that he doesn't know how to treat them, but the truth is that a coach should be so friendly with the players that it would not allow him to do his job.
So, the issue with Rodrygo is that maybe Alonso sees that Rodrygo doesn't suit his playing pattern. If he’s not satisfied with Rodrygo's performances, maybe in training, I don’t think it’s that bad not to include Rodrygo in the squad. It can't just be about keeping Rodrygo, a great young player, on the bench. That’s the reason why Alonso decided to let him go — not to waste his career. I think that’s the best thing a coach can do for a young, great player: not deny him opportunities for playing time.
Every coach has their own way of treating their players, but a good coach always treats them right. I believe Alonso treats them right, just as Ancelotti did. But that will not stop them from doing the right thing. Alonso coached Bayer Leverkusen, and they were able to achieve trophies and even set records with the team, showing that he's not the kind of coach who treats his players poorly.
