The 0-0 draw between 2007 World Cup champion and runner-up, Germany and Brazil, put them in equal second place in their group. A 1-0 win over Nigeria put the Democratic People's Republic of Korea at the top of Group F, and its opponent Nigeria has been banished to the bottom of the group behind Germany and Brazil.

Group G is similar to Group F, with Norway on top, Japan and New Zealand in equal second place after their 2-2 draw, and the United States in last place after opening-minute mistakes cost it dearly in its first game.
