Mexico surprised many observers by overcoming highly-fancied group opponents Japan and England to book their place in the quarter-finals of the FIFA U-20 Women's World Cup 2010. Robert Medina's charges now face Korea Republic, with both sides entering unchartered territory having never before reached the last eight of the tournament. In the day's other quarter-final, defending champions USA take on Nigeria.

The games
Mexico-Korea Republic, Dresden, 25 July, 18.30 (local time)
While these two sides have never met at a FIFA youth tournament, the senior women's national teams have clashed on three occasions, with Mexico winning twice and Korea Republic once.

In each of their previous appearances at the FIFA U-20 Women's World Cup (2002, 2006 and 2008), Mexico never made it out of the group stage. After almost four years without a win at the tournament (their last success was a 4-2 victory over Switzerland in 2006), the North Americans finally registered a priceless three points against England, also managing to keep a clean sheet for the very first time.

Their opponents Korea Republic, for their part, have already displayed their swift attacking style and solid defence at Germany 2010, scoring eight goals so far and conceding just three. The east Asians have a top-class striker in the form of Ji So-Yun, who will no doubt once again prove a menace for the Tricolores' back line. In 13 matches at FIFA youth tournaments, the South Koreans have never drawn a match, winning five and losing eight.

USA-Nigeria, Augsburg, 25 July, 11.30 (local time)
Reigning champions USA began the tournament slowly with a draw against Ghana, but kick-started their campaign with a 5-0 victory over Switzerland and a 1-0 win against Korea Republic. Six goals in two matches tell their own story, and further underline the burgeoning talent in American women's football at present.

Nigeria also began the competition with a draw but celebrated a convincing victory over Japan in their second group match. The Africans went on to book their place in the quarter-finals with a 1-1 draw against Mexico.

Nigeria and the USA have never faced one another in youth football. They have met on three occasions at FIFA Women's World Cups (1999, 2003 and 2007), as well as once at the Women's Olympic Football Tournament in 2000, with the Americans coming out on top in each of those fixtures.

The Falconets have never won a quarter-final match at a women's tournament previously. The USA, on the other hand, have reached at least the semi-finals at every U-20 women's competition they have participated in, making the Stars and Stripes strong favourites to continue that trend.

The stat
5 - The number of goals scored by Ji So-Yun and USA's Sydney Leroux so far at Germany 2010. At the FIFA U-20 Women's World Cup 2008 in Chile, Leroux won the adidas Golden Shoe with five goals.

The words
"We didn't play as well as we know we can in our first match against Ghana, but we've improved since then. It was good that we scored so many goals against Switzerland and also that we beat South Korea to top the group. It shows we're moving in the right direction," Bianca Henninger, USA goalkeeper.
