If Alonso really lets Rodrygo go and Valverde is made RW, it is the same as destroying the line-up. While Valverde is more suitable in the CMF position which always gives a very good contribution. I am very sure Alonso has great ambitions after seeing the contribution of young players Arda and Garcia when appearing in the FIFA Club World Cup, making the coach want to use young players as Madrid's strongest engine. In fact, Rodrygo is a very good partner for Vinicius when appearing on the field. Hopefully this news will only be a rumor and Alonso does not really do all this.
One of the questions that Rodrygo has to ask himself if whether he wants to accept an uncertain situation for himself. If he expresses his opinion on the matter and he wants more playing time but it is unlikely for him to get it, it could be possible that both parties agree to part ways. It is less likely though that Real Madrid would agree because Rodrygo is about as good a player as they can get to fill the role as a substitution player. He still has to go until 2028, which gives Real Madrid room to find a new player within the next 12 - 24 months while having great quality and they don't have to fear to be out of strikers or wing players during the season.
