The U.S. defense held strong against Ghana, but today's match will hinge on two things. First, how will the United States replace Jozy Altidore? If it remains in a 4-4-2 formation, my choice would be Aron Johannsson with Clint Dempsey to start, with a late cameo from MLS poacher Chris Wondolowski. Another interesting option is a false-nine with Clint Dempsey alone up front. Secondly, will the U.S. contain the Portuguese counter-attack? Bradley, Jermaine Jones, and local hero Kyle Beckerman will have to break up play, shield the back four, and more importantly, not give away possession so cheaply in the midfield against a Portugal side that can make you pay for it.
