If possible let him just go to Saudi where his guaranteed a starting eleven and a huge pay to accompany that alongside.
No chance that Rodrygo would move to Saudi Arabia, he has the quality to play for any top club in Europe and earn a good amount of money whilst doing that, so there is no need to go to Saudi Arabia.
Rodrygo still wants to play at Santiago Bernabeu because he still loves Real Madrid very much for this reason making his departure slow even though he is interested in EPL clubs, but clubs from other leagues are also interested in him. Liverpool are still trying to sign him, but another EPL club "Chelsea" is also interested in signing Rodrygo by offering Joao Felix and Christopher Nkunku to Real Madrid as part of the transfer deal.
In my opinion, Rodrygo needs to be more realistic about his future, as his chances of staying at Real Madrid are slim as Xabi Alonso didn't include him in his plans this summer. He should be able to change his future to become a main star at another club, moving to Chelsea or Liverpool would not be a bad decision for him.
