The USA won their opener facing Ghana 2-1, where they were not overly impressive needing a late goal to secure three points.
Portugal played in the Group of Death in 2010 and advanced. To do so this time around they, probably need to beat the USA, and will be eliminated if they can't at least draw.
PREVIEW: Win and in
Thanks to Ghana's draw against Germany, the United States can qualify for the knockout stage with a win over Portugal. The Portuguese are hobbled, but they should be favored if Cristiano Ronaldo is genuinely fit.
Not only is Ronaldo banged up with knee issues, but another key player in DF Pepe is out for this match since he had a red card in the loss to Germany.
Clint Dempsey, who scored in the first 32 seconds in the Ghana match, is the key striker for the USA in this match, especially since Jozy Altidore is out with a hamstring injury.
Michael Bradley leads the USA midfield and he had a good match opener, but overall the Americans did not have a great passing match. They cannot get away with that again facing Portugal, who has a solid midfield.
The USA will really have to look for the counter-attack facing Portugal, who will be attacking from the opening whistle.
Obviously it was an advantage for the Americans to get the early goal in the Ghana match, but after they scored they played a defensive match and did not have much of an attack.
They cannot play like that again against Portugal and Dempsey and Bradley must pressure the Portugal defense that gave up four goals against Germany.
