It's true that Rodrygo, who has always been sidelined, could potentially leave. I haven't heard any concrete news about his future, but reading Rodrygo's statements, he certainly wants to stay at Real Madrid if he's made a key player and consistently played.
That means he will leave.
He's not included on Xabi's plans, he's just a substitute player who will play for few minutes. Moving to other teams aren't that bad, Rodrygo can still able to shine on other teams because he has a quality.
If he not leave now, he will just wasting his time on Real Madrid.
An underated player who is difficult to get maximum playing minutes if he continues in Madrid. Now Rodrygo must think carefully, especially to choose a club that can meet his needs as a player. The situation is quite worrying, but this is the competition, I think the possibility of Rodrygo leaving is getting bigger, after Xabi continued to keep him on the bench during the CWC competition.
