We profile one of England's Group B rivals.
If this tournament were taking place 40 years ago, Mexico might be firm favourites. Instead, they'll take their place among the other minnows.
But the sport is once again on the up in a country where over 100,000 spectators filled the Estadio Azteca to watch Mexico's Women take on Denmark in the 70s.
As hosts of the CONCACAF qualifying event, Mexico were hopeful of putting on a show. But, considering they've qualified for only one of the previous five Women's World Cups, USA, Canada and even Colombia might have been ahead of them in the pre-tournament pickings.
But success in the junior World Cups over the last decade has seen a new era for the national side and they showed that against the USA in the Final to set up their first World Cup appearance since 1999.
Lining up that day in Cancun, there were more than 20 FIFA world ranking places between the two teams and of the previous 24 clashes, USA had won 23 times, scoring 26 goals and conceding none.
However, Mexico claimed a monumental 2-1 win, a guaranteed spot in Germany and perhaps the belief they're finally ready to take on the world.
Back in 1970, at an unofficial women's world championship, Mexico finished third. Then a year later in a similar tournament, they claimed second. Those were the heady days for Mexico's women but, if the past 12 months are anything to go by, they could be on their way back.
