Well, you posted the correct link, but this was not a month before the opening ceremony, it was 2 days... and it was not an Olympic qualifying match, but the actual 1st game of the Olympics. Remember - womens soccer started 2 days early (The Korea faux pas was the same day the Americans beat the French).
