The United States, among the tournament favourites, were held to a goalless draw by Sweden on Friday as all remains to play for in their Women's World Cup Group D.

The Americans, who started with captain Abby Wambach on the bench, were given a tough test by the Swedes who played to a 3-3 draw with Nigeria in their opener.

Wambach came on after 67 minutes, providing a lift for the Americans who played on front of thousands of fans who travelled the short distance over the border to Canada to support them.

Australia beat Nigeria in the Group D clash earlier on Friday thanks to two goals from Kyah Simon.

The United States lead the group with four points followed by Australia with three with Sweden on two and Nigeria bottom with one.

In Tuesday's final round of group games in Vancouver's BC Place Stadium the United States will play Nigeria while Sweden take on Australia in Edmonton as they bid for a place in the last 16.
