If he's not in Real's plans, Rodrygo leaving would be beneficial for him. Many clubs would want him. If he wants to leave, there are plenty of clubs in the Arabian League interested in him.
He's a useful player, but as far as I can tell, he doesn't fit into Alonso's system.
Rodrygo is so young and talented to move to the Arabic league too soon. There are many club in the EPL, Serie A, La Liga and I mean top clubs who would love to see him in their squad.
And to be honest, despite the fact that there are many options for Xavi Alonso, he should try consider giving Rodrygo more playing time and see what he is missing out. But if he still insist on not playing him, why not let the young lad go. The story between Xavi Alonso and Rodrygo is not pure yet.
