My opponent's got a real point that Mbappe's career is young, and that's genuinely exciting. But that cuts against them, not for them. Better isn't about potential, it's about what you've actually done, and Messi's résumé is already written. Also, Mbappe won that 2018 World Cup at nineteen, but he wasn't carrying the team the way Messi carries Argentina. Imagine judging a rookie ahead of a legend just because the rookie might match him someday. Possibility is thrilling, but it isn't proof. Right now, Messi is still better, and that's why I'm against.
