Both Ghana and USA can give a very good fight against Argentina, but I think Ghana could marginally cause more problems. Their very fast pace and counter attacks can do a lot of damage to the slow Argentina backline.
The Americans too, they are equally impressive, I must say. But before that, Argentina has to beat Switzerland or Ecuador first.
Argentina better beat or tie Nigeria next game, otherwise they will play France and then Germany.
