I'm also surprised that Real Madrid is opening the door to a player like Rodrygo, even though he's still very young and can still be relied upon in attack, even though they already have several better attacking players. But Real Madrid can still use him when other players suffer mid-season injuries, as happened last season, which hampered Real Madrid's consistent performances in La Liga and the Champions League. And if Madrid can't keep Rodrygo next season, the player could find another team willing to take him, especially teams in the Premier League or Serie A.
Madrid's new manager believes that Rodrygo is not suitable for his match strategy. And that is why Madrid has decided to sell ROdrygo. Madrid management is conscious of the cost. Madrid is not willing to pay high wages to keep unnecessary players in the squad. Also, Madrid can earn a large amount of money by selling Rodrygo.
I do not see the possibility that Madrid will suffer a loss if they sell Rodrygo. Rodrygo is a talented player, but I do not think that his contribution to Madrid's squad is very high. Rodrygo only scored 6 goals in 30 matches last season. I think Garcia will be able to score more goals if he gets enough opportunities.
