The U.S. Women's World Cup Team heads into its final match in Group B at the 2007 FIFA Women's World Cup in the position afforded a team that took four points off two of the best teams in the tournament during its first two matches. The USA faces Nigeria on Tuesday, Sept. 18 at 8 p.m. local (7:55 a.m. ET on ESPN) needing a win or a tie to advance to the quarterfinals.

As the USA is knotted with North Korea atop the group - both teams have four points, four goals scored and two allowed - the group title is still up for grabs. The North Korea-Sweden game will be played in Tianjin at the Olympic Center Stadium simultaneously with the U.S. game. In perhaps the most competitive Women's World Cup ever, where only one team won its first two games (that being Brazil, although its first match was against New Zealand), the USA is looking to emerge from the tournament's most difficult Group B in first place.

While sometimes confusing, the tie-breakers for FIFA tournaments are pretty simple. If two teams are tied on points, goal difference (goals scored minus goals allowed) is the first tie-breaker, followed by most goals scored. If the USA and North Korea post the same score line in victories or ties on Tuesday, they would be knotted on every tie-breaker and the group would then be determined by Fair Play points, in layman's terms, who has less yellow cards (and/or red cards). The USA currently has one yellow card. North Korea has two.
