A Premier League team could sign him. I think he'll most likely go to the Premier League anyway if he leaves Real Madrid. He's a Brazilian winger with the potential to play for any team in Europe. I honestly don't understand why he's not in Xabi's plans. A player like him absolutely needs to be on Real Madrid's roster. However, if Real Madrid wants to sell him for a significant sum, that could change.
It would have been good for Rodrygo to move to the Premier League this season, but Real Madrid hasn't received any offers for Rodrygo since Xabi Alonso told Rodrygo that he's not part of his plan at Real Madrid, so Rodrygo might likely remain at Real Madrid. Rodrygo didn't fit into Xabi Alonso's style of play; that is why Rodrygo isn't part of Xabi Alonso's plan at Real Madrid.
