The United States and Canada will do battle in the semi-finals of the women's football tournament at Tokyo 2020 after edging into the final four.

USA - winners of the Olympic tournament four times previously - managed to beat the Netherlands 4-2 on penalties in their quarter-final after the game finished 2-2 at the end of extra time.

Having finished with fewer than six points in the group stage of a major event for the first time in their history, the USA knew a much-improved display was needed against a Dutch side who scored 21 times in their opening three games, the most of any women's side at a single Olympics.

They duly delivered a strong display as they twice took the lead only for Vivianne Miedema to continue her sensational form, scoring twice to cancel out goals from Samantha Mewis and Lynn Williams in an engrossing contest in Yokohama.

Megan Rapinoe swept the decisive penalty kick high into the net after Alyssa Naeher had made two stops to her right.

BRAZIL FALL SHORT AGAIN

Canada await USA after they inflicted further heartbreak on Brazil, whose wait for gold in this event goes on.

Beaten semi-finalists in Rio five years ago, Brazil were held to a 0-0 draw before suffering another defeat on penalties to the 2016 bronze medallists.

Goalkeeper Stephanie Labbe, who was injured in the closing stages of extra time, recovered to make two critical saves in the shoot-out to secure a 4-3 win.

"In the moment, it was about trusting myself, trusting my instincts, and trusting my ability to make a save," she said afterwards.

"Pain is temporary. We have our eyes on the prize."

WHITE TREBLE NOT ENOUGH AS MATILDAS WIN CLASSIC

The stand-out quarter-final took place between Australia and Great Britain, a seven-goal thriller eventually ending in a 4-3 victory for the Matildas.

Two goals from Ellen White had turned the game on its head and looked to be enough to send Hege Riise's side through, but Chelsea star Sam Kerr levelled in the 89th minute with a crisp low strike.

The contest then swung Australia's way in a dramatic minute in extra time, Mary Fowler's deflected shot finding the top corner after Caroline Weir had a penalty saved at the other end.

Kerr scored another before White completed her hat-trick with a deft header to set up a frantic finale, with Australia just holding on for a famous win.

Remarkably, they overperformed in terms of expected goals by 3.2, their highest such figure at these finals.

Australia will contest their semi-final against Sweden, who ended Japan's quest for a medal on home soil with a 3-1 victory.

Mina Tanaka cancelled out Magdalena Eriksson's sixth-minute opener, but Sweden took control in the second half through further goals from Stina Blackstenius and Kosovare Asllani.

The United States will face the Netherlands in the quarter-finals of the women's football tournament at Tokyo 2020 after being held 0-0 by Australia to finish second in Group G.

USA bounced back from a shock 3-0 loss to Sweden in their opening game with a 6-1 win against New Zealand, but they dropped further points in the round-robin stage on Tuesday.

Previously unbeaten in 44 games before that Sweden loss, USA failed to break down Australia's defence – Alex Morgan's disallowed goal for offside the closest they came to doing so.

Mary Fowler hit the crossbar for Australia and in the end a point apiece was a fair outcome, with the Matildas also advancing to play Great Britain in the last eight.

It is the first time in history record four-time winners USWNT have finished with fewer than six points in the group stage of a major global tournament.

RAMPANT DUTCH AWAIT USA

Sweden were already assured of a place in the last eight ahead of their clash with New Zealand and saw the job through with a 2-0 win at Miyagi Stadium to finish ahead of USA.

Anna Anvegard and Madelen Janogy were on target for Sweden before half-time and they saw out a straightforward win that condemned New Zealand to a group-stage exit.

It means USA will now take on the Netherlands in the next round in what is a repeat of the 2019 Women's World Cup final. The Netherlands lost that match, but they enter this latest showdown in superb form after thrashing China 8-2 in Yokohama.

Lineth Beerensteyn, Lieke Martens and Vivianne Miedema all scored twice in the one-sided affair, while Shanice van de Sanden and Victoria Pelova were also on target.

The Netherlands' tally of 21 goals from three games is already the most scored by a team in a single women's football Olympics event, surpassing the USA's 16 from London 2012.

HOSTS JAPAN SCRAPE THROUGH

Japan did all that they could in the final round of group games by beating Chile 1-0 through a Mina Tanaka goal 13 minutes from time.

That win took the tournament hosts to four points from three games, enough to send them through as one of the best third-placed sides, along with Australia.

Already through to the quarter-finals, Great Britain snatched top spot with a late 1-1 draw against second-placed Canada in Tuesday's other Group E match.

Caroline Weir's long-range free-kick with 84 minutes played took a heavy deflection and cancelled out Adriana Leon's opener.

Brazil also booked their spot in the knockout stages thanks to Andressa's first-half free-kick in their 1-0 win against the tournament's lowest-ranked side in Zambia, who lost Lushomo Mweemba to an early red card. 

The Selecao meet Canada in the quarters, while Australia await Great Britain.

The United States returned to winning ways in emphatic fashion to kick-start their bid for Olympic glory, while Barbra Banda tied a Games record with a second successive hat-trick for Zambia.

Sweden had sensationally put an end to USA's 44-match unbeaten streak at the start of the women's tournament, with Megan Rapinoe admitting the beaten world champions had "played a bit tight" in a 3-0 defeat.

However, Vlatko Andonovski's side responded impressively to that setback on Saturday, thrashing New Zealand 6-1 in Saitama, in the process registering their largest margin of victory in an Olympics fixture.

Rose Lavelle and Lindsey Horan gave USA a 2-0 half-time lead, the latter on target to mark her 100th cap. Further efforts from Christen Press and Alex Morgan added to the score after the break, while they were helped out by their opponents scoring two own goals.

It is the Swedes who sit on top of the table, though, as a strong second-half performance sealed a 4-2 triumph against Australia.

Meanwhile, Banda equalled the record for most goals scored by a woman at a single Olympics, matching Christine Sinclair's tally of six for Canada at London 2012 with another treble, this time against China.

Zambia's captain scored all her country's goals in a 10-3 loss to the Netherlands in their Group F opener. She followed up with three more in a thrilling 4-4 draw on Saturday, though China's Wang Shuang went one better as she hit four in a see-saw contest.

Vivianne Miedema later moved level with Banda on six goals at this Olympics. The forward had scored four as the Dutch crushed Zambia, then managed another two in a 3-3 draw against Brazil.

Ellen White continued her impressive start to the tournament with the winner as Great Britain defeated hosts Japan 1-0 to qualify for the last eight.

Having scored twice in the opening 2-0 win over Chile, White made it 13 goals in her past 14 international outings when heading in a cross from Lucy Bronze in the 74th minute.

Also in Group E, Canada overcame Chile 2-1 thanks to a brace from Janine Beckie, putting them second in the standings ahead of a clash with Team GB to finish the round-robin stage.

Reigning champions Brazil and 2016 finalists Germany have been drawn together in the group stages for the men's football tournament at the Tokyo Olympic Games.

Brazil secured the gold medal on home soil in Rio five years ago when defeating Germany via a penalty shoot-out, Neymar with the clinching spot-kick for following a 1-1 draw after extra time.

The two nations are together again in Group D, along with Ivory Coast and Saudi Arabia, and are in the same half of the draw as Argentina and Spain, who are both in Group C.

Hosts Japan are joined in Group A by France, Mexico – who claimed the gold medal at the 2012 Olympic Games in London – and South Africa.

Les Bleus will be involved in the opening match when they take on Mexico on July 22 at Tokyo Stadium, followed by Japan taking on South Africa at the same venue later that day.

In the women's event, the United States – winners of the 2019 World Cup - are paired with Sweden, who lost the 2016 final to Germany. Trans-Tasman rivals Australia and New Zealand complete the line-up for Group G.

Japan will take on Canada, Great Britain and Chile in Group E, while the other pool contains China, Brazil, the Netherlands and Zambia.
