Win over USA the focus for De Vanna

As much as she would love to leave a legacy, Australia co-captain Lisa De Vanna's focus is on the Matildas and their aim to shock United States at the Women's World Cup.

De Vanna is set to make her 100th 'A' international appearance in the Matildas' opener against the US on Tuesday morning (AEST).

The 30-year-old has scored 35 goals in her 99 games, but it is a win over the Americans that she wants.

The Matildas are without a victory over the US in their 25 previous clashes and De Vanna is eager for that to change.

"For me it's all about, personally, leaving a legacy and leaving the team to the best they can possibly be," she told a news conference.

"Obviously winning that game … we've never beaten the US before, ever, and to do it at a World Cup in front of millions of people and being the captain, you can't put a fairytale ending to that.

"It's the three points we want. The captaincy and the 100th cap is not as important because I feel if we go out and get those three points it's a statement to the world that Australia is here to take on the world."

De Vanna said the clash against the US was no more important than upcoming Group D matches against Nigeria and Sweden.

As for the milestone, she said: "Every game I play for the Matildas I wear my heart on my sleeve and to finally make it to 100, it's a big milestone.

"It's hard to focus on that when you've got such a big game but it's a great honour and to be co-captain of this team just caps it off."
