Every coach has different tactics and different player selections, and it's undeniable that Rodrygo is a quality player, but Xabi Alonso has his own preferences.
Right now, there's no other option for Rodrygo than to move to another team. Even if he stays at Real Madrid, he won't be able to secure a starting spot, which would hinder his career development. He's still very young, and there are still many possibilities for his career, so I have little hope that Rodrygo will move to another team.
I agree with this and most persons are failing to understand that a player can be really okay and good but does not fits in the coaches preference and that alone make make the coach not wanting to work with that player yet it has nothing to do with the players form a.d this is the case with rodrygo and xabi at Madrid. In situations like this, it is only beat for the player to move because if he stays back he may not get good play time and may gradually loose his form.
$weetne$$ is right, for instance Antony was a good player at Ajax but wasn't very good when he switched to Manchester United he didn't even suit the new coach Amorim system but went to Betis to become a star player and was nicknamed the goat there. So not every player would suit a coaches pattern no matter how skillful or good the player is in the eyes of the viewers if such players lack some certain qualities needed by a coach he won't use the player.
