Rodrygo is indeed a very good player, as has been proven, but securing a starting spot is very difficult due to the fierce competition in Real Madrid's attack. Therefore, it would be better for Rodrygo to move to another team, as it would be in the best interests of his future career.
Rodrygo is still quite young and has a long career ahead of him at Real Madrid. If he is patient and continues to improve individually, I'm sure he will gradually earn his starting spot, although there are many rivals for a key role at Real Madrid. Xabi Alonso's journey in the Champions League will certainly be challenging, as many teams are now starting to make changes to strengthen their teams in the competition. The first season won't be smooth sailing, as Xabi Alonso may need to adjust.
