Me too.
The Japan/Australia match can go either way. The Aussies are tough dudes, so they'll probably play really physical against the skinny Japanese, but Japan showed against Germany that they have a lot of potential, and their coach is the legendary Zico!
Czech beat USA, I can see the Czech Republic being the first "big" football country to easily win (Germany hard time with Costa Rica, Netherlands - Portugal - England win with only 1-0, Mexico have hard time with Iran). I don't see USA going "far" like last time World Cup.
Italy will have a harder time with Ghana. I have faith in Ghana, I think they are able to pull off a shocker with a bit of luck. But it's Italy and they ALWAYS have luck, so they'll probably win 2-1.
You tell South Korea that.....
My memory is vague, care to elaborate? Did South Korea beat Italy in 2002 or something?
