Obviously USA was superior to Portugal, every team is superior to Portugal ATM. The guys can't even run, it's ridiculous. I would bet my house against them vs Ghana.
Portugal have 10 injures, not only Ronaldo (and i don't see anything specially wrong with him FWIW, sure is not 100% but, cmon, what exactly were people expecting him to do with this team? Dribble 8 players from the midfield and score?), "half" the players in that start eleven didn't play this year because they were injured or they were second/third options in their teams.
I'm sure some people here are aware Portugal was 4º in the World ranking before the tournament, like Spain was 1º, it wasn't because they usually play like this.
It's never smart to make conclusions about a team based on two games. It's like saying the Miami Heat are totally garbage based solely on the last 3 (ok, 5) games of the NBA finals.
Oh, i'm Portuguese, if there was any doubts about it, and i'm embarrassed by the lack of effort display by "my" player (don't get me start talking about Pepe). Losing i can accept, what else can i do, but being run over by other teams and not giving it all is unacceptable.
