Soccer is a team sport. You can do everything right, do everything the best, and never win a trophy. But, if you win a trophy, no one remembers your failures. No one remembers that Maradona was held scoreless in 78% of the games he played for the National Team, that he didn't score a goal in the entire 1990 World Cup or that he was actually held scoreless in the 1986 World Cup Final. Why? Because his teammates rose to the occasion in
one game: the 1986 WC Final. And so, because he hoisted the trophy, he is cemented in the minds of non-Argentine fans as an all-time great.
Maradona's accomplishments at the international level are a fraction of that of Messi's. He isn't even a Top 2 player in Argentina National Team history, even with his '86 WC showing. The two best, without any question, are Messi and Gabriel Batistuta. Look up the most combined goals & assists in Argentina's tournament history and Maradona shows up 2 times in the Top 15. Messi shows up 7 time! Only once in 8 tournaments has Messi failed to score at least 2 goals. Maradona failed to score at least 2 goals in 5 of 7 tournaments. Messi has goals per game than any Argentine in National Team history, more assists per game than any Argentine in National Team history, cup Finals than any Argentine in National Team history, more cup "MVPs" than any Argentine in National Team history. He owns the Copa America record for assists. He owns the Argentine record for World Cup goals and assists. All told, he has 71 goals in 128 NT games vs 34 goals in 91 games for Maradona. And, he's been to 5 cup finals vs 2 for Maradona.
If Higuain hadn't bottled the one-on-one he was gifted vs Neuer or hadn't been a hair offside on the goal he scored in the 2014 World Cup Final.......if he hadn't missed an open goal from 3' on a beautiful pass from Messi or missed his PK in the 2015 Copa Final...........or if he hadn't missed an empty goal on Chile's defensive error in the 2016 Copa Final.........Messi has a trophy and we're not even having this discussion. But, why is Messi's brilliance for the National Team overshadowed by failures of his teammates, but Maradona's failure for the National Team are glossed over because his teammates capitalized in the '86 World Cup? Does Higuain failing to capitalize change any of what Messi did in international play? You can't own every record worth owning, for both your country and in tournament history, and not be the GOAT at international play. Also, it's worth noting, Maradona had just 3 managers in his 17 year National Team career. Messi has had 9 in his 16 years! The best Argentine managers of Messi's era have all refused to coach the NT because of the incompetence and corruption of the AFA. That wasn't the case in Maradona's era. They had great managers and continuity.
