What?
Argentina in WC 2018 faced 3 teams Portugal had in Euro 2016: Iceland, Croatia and France. And Argentina didn't win any of those games.
And that super Chile that eliminated Portugal in the semis lost the Confederations Cup final to the literal subs of Germany
Ronaldo being bad vs South American teams is an interesting take since he had so many games vs them: 3 competitive games (1 vs Brazil, 1 vs Chile and 1 vs Uruguay) and 5 friendlies (2 vs Brazil, 2 vs Argentina (1 goal), 1 vs Ecuador (1 goal)).
What a sample!
Also that Croatia was finalist of WC 2018, as well as France. Basically the final of WC 2018 was basically 2 teams Portugal had to eliminate in Euro 2016
