Quarter Finals: Spain beat Croatia modestly Lithuania beats China fairly easily USA beats Australia easily Greece beats Argentina barely
Spain beats Lithuania modestly USA gets crushed by Greece (just kidding, the US should win this, but you know who I will be rooting for)
Final USA beats Spain
Now these are all fairly conventional predictions except for Greece-Argentina where Argentina is favored so at least one will be wrong.
So far there have been few surprises. With the possible question of Australia, these are the best 8 teams in the world.
