The U.S. is the No. 1 team in the world, a two-time World Cup champion and three-time Olympic gold medalist.

The only number that matters right now, however, is zero.

As in, the number of World Cups the current team has won.

The Americans have to get into gear if they don't want to go home empty-handed again. After losing a group stage match for the first time at the World Cup, they must play old foe Brazil in the quarterfinals Sunday, a matchup most had penciled in for next weekend's final. Lose, and it will be the Americans' earliest exit ever at the biggest event in women's football, a tournament they last won in 1999.
