Argentina, unlike Portugal, play for each other and actually play as a team.

Portugal may have the better midfield on paper, but Argentina are absolute dogs.
They don’t spend 30 minutes romanticizing the ball without any penetration. They attack and play direct.
They also do everything they can to help Messi. No one complains when he misses a penalty or doesn’t track back.
That semifinal against England is going to hit like crack.
