Steph Houghton is already looking towards England’s second World Cup match following their 1-0 loss to France in Moncton.
Eugenie Le Sommer scored the only goal of the game to consign Mark Sampson’s squad to an opening-day defeat at Canada 2015.

Houghton said: “As a squad we are feeling positive. We can come away from the game with our heads held high.
“The preparation for Mexico starts tonight. We will recover properly and be ready to produce the goods at the weekend.
“We’re ambitious. We’ve got winners in this side. Every time you play for England you want to win.
"We are going to go into the Mexico game feeling positive. Now is the time for us to kick on and hopefully get three points.
“We have to be upbeat.”
Lucy Bronze was employed on the left wing in Sampson’s 4-1-4-1 formation to stifle the pacy Elodie Thomis.

It was a tactic that worked as the ineffective France forward was hauled off midway through the second half.
France are ranked third in the world and can boast recent wins over USA and Germany, sides ranked one and two.
And, despite the result, Houghton was satisfied with her team-mates’ discipline.
She added: “We are disappointed to lose but we have to take the positives out of the way we performed. We stifled France and their world-class forwards.
“Every single player stuck to the game plan. We needed a little bit extra going forward but we had to respect France.
“They are third in the world and are in-form, so we have to take the positives and move on to the Mexico game on Saturday.”
