Yes, there are rules just like in our football, North American football.
I see a separate thread has been set up for USA/Portugal.
I really think momentum is with the USA, maybe Portugal has superior personnel but I really think the USA will win today. 2-1.
Korea probably remains alive in the World Cup after this game with 1 point from their draw with Russia. But it will be tough for them.
I think all of the teams have a chance, Belgium must already be advancing and Algeria very close.
