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.
Carlo Ancelotti had his own players and he was one good manager for the club side. He was able to ensure he sealed every move for upgraded performance and he's basically an important manager for the club. Real Madrid have quite good numbers of incredible players with magnificent performance.
Concerning the case of Rodrygo, he's big game player and his presence is felt in the club. This is the kind of player that every elite club needs, there's no going back when there's this specific player in the club. However his presence is been under probability following the new manager signed for the club. Let's see how things goes from here.
