Okay, since Yamal is Luffy and Messi is Shanks, who do we assign as their crewmembers, folks? Who are the Zoro, Lanji, Jinbe, and other SHs of Spain? Who are Beckman, Yasopp, Roo, and others RHPs in Argentina?
Argentina has produced someone on Messi's level twice with him and Maradona. What makes you think Argentina can't do it again and again? Once might count as a coincidence (like Brazil & Pele), but twice is a pattern. Expecting someone on the level of Maradona and Messi from Argentina again to arrive in a decade or so should be considered acceptable.
