Great Britain coach Hope Powell is wary of the threat of Canada in the Olympic quarter final after maintaining their 100% win record after beating Brazil in front of a record Wembley crowd for a women's fixture.

The 70,584 Wembley crowd inspired Team GB to victory over a Brazil side who will face world champions Japan in the last eight.

Britain will take on Canada in the quarter final, who won just one of their three group matches, but Powell isn't taking anything for granted despite their three group wins being accompanied by consecutive clean sheets.

Powell is wary of the Canadian threat.

"It gave us an edge, it was fantastic," said Powell.

"Usually when I talk on the sidelines the girls can hear me, but this was a good excuse for them to ignore me.

"The atmosphere was electric and we got off to a great start. We spoke about it beforehand, about keeping the momentum going.

"Personally, I wish I could thank every one of the supporters.

"We are trying to leave a really positive legacy. I read somewhere that the Olympics was a platform to do that and I think that against Brazil we partly achieved it."

"Canada are a decent side, their group was tough," she added.

"I went to Switzerland to watch them a couple of weeks ago when they played New Zealand and I have come up against them a couple of times before as England coach.

"It will be a hard contest. I know their manager John Herdman and their fitness levels are 10 times better than they used to be."

Ranked seventh in the world rankings, Canada drew 2-2 with Sweden in their final group game, having beaten South Africa and lost to Japan during their Olympic campaign.

While Great Britain are competing in the football competition for the first time, Powell brings 14 years worth of experience as England coach, reaching the final of the European Championship in 2009.

Full back Steph Houghton netted her third goal of the women's competition, after scoring in the wins over New Zealand and Cameroon, and she admitted after beating Brazil she couldn't believe the team's achievement.

"Did that just really happen," she explained. "But you know what, we could still be out there playing now because that is how confident we looked about getting the win.

"Everyone was thinking that Brazil were going to beat us but we can take belief from that result and we think we can beat anyone in this tournament."
