This is my prediction
USA to advance. Belgium barely climbed out of their group, and were very close to losing to Senegal, but made a fantastic last minutes comeback and won in extra times. They cant keep it up with the game they show.
As a surprise
Belgium to win from behind
As a surprise
Belgium won 3-2 against Senegal, and 5-1 against New Zealand before that. They score well, but defensively team plays poorly. USA played high scoring 3-2 match against Turkey. I think teams will exchange goals qucikly.
