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.
Rodrygo should definitely go to a new club. We have already seen that Rodrygo is not part of Xabi Alonso's match plan. He is more interested in using garcia. So rodrygo has no chance of getting a place in Madrid's starting XI. If mbappe or vini face injury then maybe rodrygo can get a place in the starting XI.
If rodrygo is not in Madrid's starting XI , it will be bad for his career. Rodrygo's performance will gradually deteriorate. And it will be very difficult for Rodrygo to join a rnenowned club in the future. So Rodrygo should leave Madrid this season
