It is exciting to see how well Gonzalo Garcia is playing at just 21 showing he could become major goal scorer for Real Madrid in future.
As for Rodrygo it is shame he only played for 4 minutes in that game which makes it hard for him to shine and fuels transfer rumors. However like your friends say it seems unlikely Real Madrid would sell him unless he really wants to leave because he is valuable player with unique skills like dribbling and scoring important goals. Real Madrid needs his talent for their team to be strong so it is good guess that Rodrygo will stay with club.
