GIF: U.S. keeper Howard makes a stunning save

The United States fell behind early against Portugal after a blunder Geoff Cameron was pounced on by Nani. 

Since then, however, the Americans have been on the front foot, registering a myriad of chances. Portugal launched a push back before the end of the first half, requiring Tim Howard to make a stunning save on a shot from Portugal's Eder after Nani's initial effort was misplayed by the American goalkeeper.
