... Not nice comments? Dude, you haven't seen not nice comments if you think that me telling you you're living in an alternate universe if you think that Ghana are favorites in that match is not nice. If a favorite in a match is defined as the team who has a general concensus behind them to win (that is, the media, etc., thinks they're going to win), then I have yet to see anyone who thinks that Ghana is the favorite.
That said: I think Ghana could win, they're just definitely not favorites at this point. What's good about the Ghana team is that they play great defense (as demonstrated by the Germany game), which is something that Uruguay doesn't do. On the other hand, Uruguay has two of the best attacking players we've seen in the World Cup in the Forlán / Suarez duo. Ghana didn't score a single goal in normal play in the group stage (i.e., two penalty kicks). I just can't imagine them being favorites.
Also, unless the Netherlands shows better stuff in the game against Brazil they won't beat Brazil. Their back 4 isn't very good compared to Brazil's very good back 4 and super attacking force. Brazil looks like the only championship quality team we've seen aside from maybe Argentina, but I'm still not a true believer there yet.
