At first glance, given the selection, probably this...
I was tempted to think 3-5-2 for this occasion only... but the best way to take pressure off a makeshift backline is to A) give them a quick gate-keeper who will stay home & B) keep the ball at the other end. And working attack from the left with this crew gives us two outstanding back side targets to help Altidore consume defenders.
Of course, I'm also not in training to see how everything looks and tinker. So there's that.
UPDATE: Forgot Mr. Guzan. Fixed.
