Well, despite a minimal loss to Germany, and with only 4 points of possible 9 gained, USA is through to the round of 16, whilst the current world champs Spain, as well as previous cup winners England and Italy, are not... Deservedly so, I might add!
Belgium might be a tough nut to crack in that match, but from what they've shown thus far, I believe USA can win...
The problem, however, is the most likely opponent in the quarter final... Lionel Messi
