In my opinion, Rodrygo should stay at Real Madrid, he should be more patient, the league hasn't started yet and it seems to me that the new coach is still experimenting with the squad to have a definitive formation and players who will always be the ones to start the game. He probably still wants to see what the best position is for Rodrygo and Viciniu Jr. because both of them haven't been able to score goals consistently.
I don't think you've read it your reading the hand writing on the wall, Rodrygo isn't needed by the coach and clear. If you're needed the message would be passed across, Guler wanted to leave as he wasn't normally used by the then coach Ancelotti. Last season transfer window, he wanted to leave but Ancelotti said no that he will use him pre often than the previous season. Rodrygo was ahead of Guler in the selection order. At the end of the campaign, Guler wanted to leave and when Real Madrid appointed Alonso, he dropped a message that Guler should not leave that he will be used in his first team. That's why we have not heard of any Guler rumour of leaving again but that of Rodrygo.
