After Al Nassr committed €500 million to Ronaldo, he also made it a condition that the club bring in strong signings. It seems Ronaldo is now trying to bring Rodrygo to Al Nassr. Hopefully they sign him, because I think if Rodrygo joins Arsenal, he may disrupt the team chemistry. Apparently, Real Madrid is asking €90 million for him. Arsenal shouldn't be paying that kind of money anyway. One thing is clear, Rodrygo's Real Madrid career is over. He will definitely be transferring to another club in this window.
It's clear that Xabi Alonso has no plans for him in the first team if he decides to stay and fight for his place then he'll warm the bench mostly except he has to work hard to be versatile enough for Xabi Alonso to use him as a wingback but it's almost impossible since Arnold suits that wing perfectly, I support your statement that the best option for him is to leave now, the earlier he realises the better for him else he'll go from being one of the super stars of Madrid to a bench warmer when the new season starts. Agent Ronaldo would try to persuade him to dump Arsenal for Al Nassr and the offer they'll table would play a role to him joining the Saudi League.
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.
