Speed the key for Matildas

Australia forward Samantha Kerr believes the Matildas' pace up front can trouble United States at the Women's World Cup.

The Matildas have a difficult start to the tournament in Canada, taking on USA in Winnipeg on Tuesday morning (AEST).

USA enter the Group D clash as favourites, but Kerr feels there are areas the Matildas can exploit.

"We've got a lot of speed up front, it's no secret," she told reporters.

"We're a speedy team, I think everyone knows that. We've got great midfielders.

"If we stick to our game plan, we think we have the patience and the ability to break any team down."

The Matildas are in the Group of Death, with Sweden and Nigeria their other opponents.

Kerr played down the significance of the USA clash, as much as Australia would love three points.

"It's important to get a win obviously," she said.

"But if things don't go to plan it's not the end of the world, there's still two games left and we need to win those too."
