United States men's basketball coach Gregg Popovich insists his side's defeat to France in their first outing at Tokyo 2020 should not be considered a surprise result.

Team USA have won gold in the last three Games, but they saw a 25-game winning streak in the tournament come to an end on Sunday against an inspired France side.

Les Blues, who also beat a much-fancied USA in the World Cup quarter-finals in 2019, are ranked seventh in the FIBA rankings but proved too strong for the world's top team with an 83-76 win at the Saitama Super Arena.

Despite his side's long unbeaten run in the competition coming to an end, Popovich – taking charge at his first Games – was quick to put the loss into some perspective.

"People shouldn't be surprised that we lost to the French team or the Australian team or the Spanish team or the Lithuanian team," he told reporters.

"It doesn't matter who it is – the gap in talent shrinks every year, as there are more and more great players all over the world.

"And you need to give the French team credit for playing well. They were more consistent than we were at both ends of the court. It's as simple as that."

Team USA 25-game winning streak Olympics

STARS ALIGN FOR HISTORY-MAKING ZOLOTIC

Sunday was a positive day on the whole for Team USA – especially compared to Saturday, when they failed to win a medal on the opening day of a Games for the first time since Munich 1972 – as they picked up four gold, two silver and four bronze.

That haul includes a maiden gold in the women's taekwondo thanks to teenager Anastasija Zolotic, who beat Tatiana Minina of the Russian Olympic Committee (ROC) in the final of the -57kg weight category event.

"My eight-year-old self was running around the schoolyard saying I was going to be Olympic champion but she could never have imagined what this moment is like," Zolotic said.

"It's unbelievable. It really hasn't sunk in yet. I can't believe it. I'm in a bit of shock. I'm just trying to wrap my head around it. It feels wonderful. I came here confident and ready to take the gold. The stars were aligned."

Zolotic's win came on the back of two-time Olympic champion Jade Jones suffering a shock elimination to Refugee Olympic Team member Kimia Alizadeh in the last 16, denying the Team GB athlete a shot of winning a historic third gold.

BILES BOUNCES BACK, CHUSOVITINA WAVES GOODBYE

A lot of focus has been on Simone Biles heading into the Games, though she had a rare off day as the USA finished behind ROC in the women's gymnastics qualifying.

Biles, who won four golds and a bronze in Rio, was penalised on both floor and vault but still scored a respectable 14.166 to book a spot in the final.

While Biles still has time on her side, both in Tokyo and in the long term, the 2020 Games will be the last for Uzbekistan's Oksana Chusovitina, who bowed out on Sunday after a record-setting eighth appearance at the Olympics.

Chusovitina, at the age of 46, just missed out on qualifying for the vault event and was given a standing ovation by the small number of people inside the arena.

To put Chusovitina's remarkable run of appearances into perspective, she made her debut at the Games in 1992, some five years before Biles was born.

"It was really nice. I cried tears of happiness because so many people have supported me for a long time," she said. "I didn't look at the results, but I feel very proud and happy. I'm saying goodbye to sports. It's kind of mixed feelings.

"I'm alive, I'm happy, I'm here without any injuries, and I can stand on my own."

KEEPING IT IN THE FAMILY

Japanese pair Uta and Hifumi Abe made Olympic history as they became the first siblings to win gold medals on the same day of a Games in an individual sport, both enjoying success in judo on day two in Tokyo.

Uta won the women’s 52kg competition, defeating France's Amandine Buchard. A closely contested bout went to a golden score, with Abe crucially claiming ippon to settle the final in her favour.

The two-time world champion cried tears of joy in the aftermath, admitting: "I don't know, maybe it may not have been appropriate but I couldn't hold myself back."

Older brother Hifumi made it a family double, overcoming Vazha Margvelashvili of Georgia to triumph in the men's 66kg final.

"This has turned out to be the greatest day ever," he said. "I don't think we, as brother and sister, could shine any brighter on this stage known as the Tokyo Olympics. I'm so happy."
