Well for one thing Uraguay is a better side collectively, defensively and they capable of taken their chances, you looking at a quarter finals team here, same thing he did for Atletico, dont rule them out.
Meanwhile Argentina have an almost perfect history against Mexico, I expect them to underestimate this el tri side and pay the ultimate price for it. USA will look to beat Ghana, they usually do thier homework spot on as we saw threw the big six, bet your bottom dollar they will have a game plan come saturday.
