The Copa America
Many Argentines felt that Messi didn’t belong in the same category as Diego Maradona. That’s because he didn’t enjoy any international success with the national team. He retired because of the pressure and exhaustion that he felt from representing them without winning anything.
However, Messi returned and won Copa America in 2021. Argentina won South America’s biggest international event in the home of their arch rival Brazil. It was also Messi’s 10th major tournament with his nation and changed his status there. It made him a diehard favorite at home for the first time in his legendary career (via BBC).
