None of the 8 teams that have played so far have impressed me very much, but that's usually the case in the first days of a World Cup. Argentina were good in the first part of their game against Nigeria, but, as Van Basten II said, they lost steam later on; some of their players looked very tired. Greece were the weakest team by far, while South Korea were better than I expected. I'm looking foward to the England v United States game later today.
