That's a relative thing though, isn't it? He's played in Argentina sides that have reached four international finals, and few would argue they were vintage Argentina sides at the time. There's massive selective memory.
Portugal were 8th in the world rankings at the time of their Euro win, for instance. To get to the final, they drew with the 34th, 20th and 10th best sides in the world in the group stage (coming 3rd in the group of 4), before beating the joint 27th best team after extra time in the 16s, the joint 27th best team on penalties in the quarters, and the 26th best team in the semis. They then beat 17th ranked France in the final, with Ronaldo going off injured early on. So they drew 5 of their 7 games after 90 minutes, and didn't beat a single side ranked higher than them, yet Ronaldo is great coz he dragged them to the win. Luck is luck however you look at it.
As a point of contrast, in 2014 Argentina were ranked 5th in the world. En route to the final, they beat the 21st, 43rd and 44th best teams in the group stage to top their group, before beating 6th placed Switzerland in the 16s, 11th placed Belgium in the quarters, and 15th placed Netherlands in the semis, before losing to the 2nd ranked Germans in the final. So once again, they got to the final by playing one other team from the top 10 of the FIFA rankings. Is it really an elite tournament?
