of course I also agree if Rodrygo moves to the Saudi League to accompany Ronaldo at Al Nassr because if Rodrygo continues to be a reserve player at Real Madrid it is certainly very unfortunate because he is a star player. but of course if Rodrygo moves to the SPL of course he will get full attention and of course it will make Rodrygo's name remain popular because he will work together on the field with Ronaldo.
but of course in my opinion Real Madrid also actually needs Rodrygo even though there are other great players because of course in my opinion with Rodrygo at Real Madrid of course it will make Real Madrid a stronger team because for example if there is a player who is injured of course Rodrygo can replace him. but of course according to the news I read from the internet of course the final decision is after the club world cup is over only then will there be certainty whether Rodrygo will leave Real Madrid or not.
If Rodrygo played in the Saudi Arabian league, that wouldn't be a bad thing, as he would certainly be a mainstay there and would also receive a very high salary. However, Rodrygo still seems to want to carve out a career in Europe, as he's still young, so even if he left Real Madrid, it wouldn't be difficult for him to find a new team. Furthermore, I once read a news article about Rodrygo's assumptions about leaving Real Madrid. He said that if he left Real Madrid, he would only want to play for Arsenal. I don't know if that's true. But if it's true, I think it's clear that Rodrygo still wants to play for a top European team.
Besides that, if we think about it more deeply, Real Madrid certainly still needs Rodrygo. Because, as you said, Rodrygo can replace players who might be injured. But that's not what Rodrygo wants. If he stays at Real Madrid, he wants to be a mainstay, not a second-string player. Therefore, if Real Madrid insists on not giving Rodrygo much playing time, I think even if they want to keep him, I think Rodrygo himself will choose to leave. Because he'll surely think why stay at Real Madrid if he's only going to be a second-string player. Therefore, we'll have to wait for a decision on this matter after the Club World Cup is over.
