I wouldn't support the move of Rodrigo to SPL, because he is still very your and needs to create records for himself and win European trophies. If he goes to SPL, he wouldn't be popular anymore, because he is still coming up and not yet famous compared to the old footballers in SPL that went from Europe clubs. Rodrygo loves Real Madrid and assuming he is meeting up with the competition at hand, he would have not think of moving to somewhere else.
A young player like Rodrigo still deserves to be at Real Madrid, and now that Real Madrid is coached by Alonso, who also really appreciates young talent, next season is a great opportunity for Rodrigo to continue his career at Real Madrid. La Liga is a very competitive league, so it can be quite good for the career path of any young player, including players like Rodrigo, who have already shown their form in several matches in previous seasons. I also still like him choosing to stay at Real Madrid with his other teammates, because next season Real Madrid must be better than last season.
Of course, I also support him to stay in Real Madrid provided that the coach can rotate players in order for Rodrigo to have time playing on the field, because if he just sits on the bench, it will affect his performance. Maybe, that's why his manager wanted him to go to another club, but Rodrigo believes in Madrid more than any other club.
