AUCKLAND, New Zealand (AP) In the words of Vietnams coach, facing the U.S. national team in the Womens World Cup is a daunting quest, something like a mountain, said Mai Duc Chung.

Vietnam makes its World Cup debut Saturday against the United States, the heavy favorites to win the tournament for an unprecedented third time. The Americans enter Saturdays game in Auckland at Eden Park with the same confidence it carried through its last two World Cup-winning runs.

The U.S. is a very, very strong team. It is like a mountain. But it doesnt mean that we will give up, said Mai.

But few believe Vietnam has a chance. The national team is very similar to Thailand, which the Americans thumped 13-0 in the opener at the World Cup four years ago in France. The United States went on to beat the Netherlands 2-0 for its second consecutive World Cup and fourth overall, the most of any nation.

Fear? We Believe, said captain Nuynh Nhu. Weve already prepared. Nothing to fear, nothing to be afraid of.

The Americans wouldnt dare discount an opponent, particularly after the criticism it took for running up the score against Thailand four years ago in France. They are taking Vietnam in the opening game quite seriously.

We want to show our respect by giving our best game, and we know that theyll do the same for us, captain Lindsey Horan said Friday, the eve of the match. I think everyone always gives us their best game.

The United States has a new cast of players at this World Cup, including 14 who are making their first appearance in soccers biggest tournament. Among them is 18-year-old phenom Alyssa Thompson and up-and-comer Trinity Rodman, the 20-year-old daughter of former NBA star Dennis Rodman.
