Three top contenders took the field.

After Australia and New Zealand, the co-hosts of the Women’s World Cup, kicked off the tournament with victories, the focus now shifts to the next games of group play, and to three top contenders taking the field: Canada, Spain and the United States.

Spain and the United States are no strangers to the final rounds of the Women’s World Cup, and they will have to withstand the pressure of having a target on their backs. Canada faces a different sort of pressure: its so-far-unrealized expectations on the World Cup stage. It played Nigeria to a draw, 0-0, on Friday.

After these games, there will be a clearer indication of which of these contenders are poised to make a championship run, and which have problems to address.

Spain, whose roster contains several players from the powerhouse European club Barcelona, has lost only once in the last year. Spain is yet another program in a battle with its federation: A truce was called before the team set off for the tournament, but tensions remain.

When Spain and Costa Rica played in the opening match of the 2015 Women’s World Cup, the Costa Ricans were able to hold the Spaniards to a 1-1 draw, a performance they’ll be looking to repeat.

Vietnam, playing in it’s first Women’s World Cup match, has odds of winning the tournament at just 50,000 to one, but the team gave the highly rated German team a scare on June 24 by keeping a friendly close — the final score was 2-1.

The United States was criticized after its opening performance in 2019, when the team beat Thailand by 13-0. In the lead-up to this Women’s World Cup, none of this year’s players would commit to refraining from a similar goal frenzy, and as a team looking to make history with a third straight title, the United State would take a win in any form.

Both teams momentarily set aside battles with their federations over investment and equal pay to play in their opening game, which ended in a scoreless draw.

Canada, the reigning Olympic champions, made the quarterfinals of the World Cup in 2015 but lost in the round of 16 in 2019. Nigeria has won the Africa Cup of Nations 11 times but is facing a stiff challenge in a group that includes the host nation Australia.

The Philippines, in its first Women’s World Cup, features a roster with 18 American-born players. It lost Friday to Switzerland, a team with only one previous Women’s World Cup appearance (in 2015). Neither team is expected to advance far in this tournament.
