Group order:
1. 4 points, Italy +2 Goal differential
2. 3 points, Czech Republic +1
3. 3 points, Ghana +0
4. 1 point, USA -3

IF Italy beats the Czech Republic, and the USA beats Ghana, the USA advances
IF the Czech Republic draws Italy, and USA beats Ghana 5-0, the USA advances.
IF the Czech Republic beats Italy 3-0, and USA beats Ghana 3-0, the USA advances.
