DRESDEN, Germany -- After meeting in the first round at the last three Women's World Cups, the United States should know everything it needs to about North Korea.
Not even close.
Then again, nobody knows much about the North Koreans.
There's a definite air of mystery surrounding the Americans' opponent in their World Cup opener today (11:45 a.m., ESPN).
North Korea plays few games, just five in the last six months, giving opposing coaches little opportunity for scouting. None of the players play overseas professionally. Only two of the North Koreans have previous World Cup experience.
North Korea is also the youngest team in the tournament, with 14 players 20 or younger -- including two 16-year-olds and two 17-year-olds -- and just one who is 30. Only five players have 10 or more appearances with the senior national team.
"It's really difficult when you don't see much of a team and you're not familiar with how they play," defender Ali Krieger said Monday after the U.S. training session at Rudolf-Harbig Stadium. "We might get some nerves because you don't know what to expect."
Goalkeeper Hope Solo said it's even hard to see footage of their games. The U.S. is basically keying off two recent North Korean games -- against Germany and China -- and figuring that's the lineup they'll face this time out.
"They are technical, they're comfortable with the ball, they're reading the game very well and I think they're one of the best teams in the world between the boxes," U.S. coach Pia Sundhage said. "But the game and the field's a little bit bigger. You have to add the two boxes."
The Americans have played North Korea three times, all at the World Cup. The U.S. dominated the first two meetings, winning each game, 3-0. But North Korea has made it a priority to improve its soccer teams, and the results are beginning to show.
At the 2007 World Cup, the Americans went down, 2-1, before Heather O'Reilly scored to salvage a draw. The North Koreans won the Under-20 title in 2006, and were runners-up -- to the Americans -- two years later. They also have won three of the last five Asian titles.
Alex Morgan is one of the few Americans who's seen the North Koreans up close recently -- though "recently" may be a bit of a stretch. She was part of that U-20 team in 2008.
"I don't remember too much. I just remember winning," Morgan said.
