Of course Rodrygo could fit into Real Madrid's plans and he has those qualities inherent in him but even then among dozens of players, he may not be getting the support he deserves with Madrid. In many cases it is clear that his priorities have dropped and he is also moving away from the manager's plans. In terms of terminology there may be a stark difference between Luka Modric and the emerging top player of Brazilian origin,Because we all know about their positional strength. In fact Real Madrid's midfield reliance was mainly on Luka Modric, so we didn't see him on the bench for much time but Rodrygo was on the bench for a long time even in important matches.
Actually Rodrygo can fit into Xabi Alonso style and tactics but the only problem is there are players which are preferable better than him in the team so they cannot bench them over him that is the reason why he doesn't starts match for Real Madrid. Also in an interview Xabi Alonso says that the reason he does not start Rodrygo is because he does not fit into his style of football . If it turns out that Rodygo leaves Real Madrid i think that Real Madrid will be losing a good player from the squad.
If Xavi Alonso has said that the player doesn't fit into his style of play then there is no reason arguing about the future of the players again leaving the club should be the Best thing to do for the carrier of the player you don't expect the player to be on the bench because obviously there are alot of players that can replace him at his position
