The referee in the Italy/Korea match deserves to be shot, but he was fair, he made bad decisions both ways. There has been some talk about how the officials are chosen, apparently, all FIFA countries can contribute one, and ony one official. So you have countries that are routinely staging world class events with one referee, and countries that have rarely hosted an international with one. That seems kind of dumb to me.
Anyways, gripes aside. The Koreans played some adventurous, busy and occasionally inspired football, and the Italians looked like a spent force hanging on to their lead after half time, sorry, but true.
Totti should not have been yellow/red carded, but equally, the dive he made was not worthy of a penalty.
Probably an unpopular comment here, but I, for one, am glad one of the host nations got through to the next round. They have shown a real grit and determination that many of the "world stars" have lost.
