Rodrygo is still young and possesses excellent individual qualities, so it's fitting that he join a team that can give him a starting spot and further develop his career.
At Real Madrid, it's already been very difficult for Rodrygo to secure a starting spot due to the fierce competition for attacking positions, and he also doesn't seem to fit into Xabi Alonso's style of play.
It's not that he doesn't fit Xabi Alonso's coaching style, it's just that Alonso hasn't tried to give Rodrygo time. Everything should be tried before being immediately judged unsuitable for any reason. Alonso also needs to have backup forwards if he wants to compete fiercely with strong rivals in major competitions next season. However, if Rodrygo's only reason for not being a starting player at Real Madrid is that he can rotate, as other forwards can easily tire if they don't get rotation in certain matches.
