I was not too impressed with the level of soccer displayed in that game. Except for Sophia Smith. She's an outstanding goalscorer.
Later on I watched Japan vs. Zambia, and it was night-and-day compared to U.S./Vietnam. Now granted that the level of the competition was extremely low, but the Japanese women still took care of their business properly, and curb-stomped them as they should. I don't know if Nadeshiko can pull off a repeat of 2011 when they won it all, but I expect them to make it pretty far into this tournament.
