After Musiala's serious injury, Rodrygo becomes a prime candidate for that position. If Bayern Munich can acquire him, it would be a huge success. Despite his lack of success at Real Madrid, Rodrygo possesses immense individual talent. A transfer to Bayern Munich could bring him to the top. Arsenal could also be an option, but given the challenging nature of the Premier League, he's more likely to win trophies there. Saudi Arabia, however, is clearly not an option.

Many Real Madrid fans are reluctant to see Rodrygo leave Real Madrid, as he's the player Real Madrid needs when they're struggling. He's often the solution; he's arguably one of Real Madrid's impressive supersubs.

However, as you said, he's still a young player with a long career ahead of him, so leaving Real Madrid is the best option for him to break into the first team. Even if he were to leave Real Madrid, it's unlikely he'd go to Saudi Arabia, as he still wants to pursue a career in Europe. I think Arsenal, PSG, and Bayern Munich are the best options for Rodrygo right now, as he's a player with potential, but unfortunately, he's been overshadowed by Mbappé and Vini at Real Madrid.

Every coach have their pattern of play, when they come into a new team with different players they never coach before, they do make some changes by choosing the players they want and make the rest of the players feel useless in the squad that is exactly what is happening to Rodrigo in Real Madrid as we speak.

Alonso said that he was going to give him playing time, but with the few matches he has already coached, it seems like he have an entire different pattern that have no space for Rodrigo in his squad that’s why Alonso made it clear that he can leave if better offer is submitted for him. Arsenal, PSG, and Manchester City are willing to sign him, one of them might be victorious if Saudi Arabian teams don’t pump in too much money to get him from Real Madrid.
