The United States plays Ghana Monday at 4 p.m. The top two teams from every group will go on to the round of 16. It will be difficult for the United States to move on because Group G is considered by many to be the “group of death.” Germany is ranked second in the FIFA world rankings. Portugal has Christiano Ronaldo, who could be the world’s best soccer player. And Ghana has beaten the United States in the last two World Cups.
