If Portugal fall flat then that leaves the door open and, having spent a bit of time with US manager Jurgen Klinsmann, I am backing them to make it out of the group.
The US will be so well prepared and their team spirit is second to none. I think they will see off Ghana and reach the last 16.

The US is going to have to get at least 4 points from Ghana and Portugal.
I think the US has a better shot at getting 3 points against Portugal, then perhaps a tie with Ghana would be good enough to get them through.
The US beat Portugal the last time they met in the WC, when Portugal was heavily favored, and Ghana has sent the US out the last two WCs.
