This looks to me like a similar case to England vs USA. Similar teams in regards to characteristics cancel each other out.
To me Argentina are known to be pigs. Yes they have some technical players but above all they have always had a lot of destroyers. In South America they have had a horrid time against Chile, a team very similar to their own who actually outdoes Argentina in toughness.
And it seems like this edition of Mexico is also just as hard as Argentina - perhaps even harder - while still possessing decent players on the technical side. Always interesting how different match ups play out.
