World champions Spain and Luka Doncic's Slovenia are set for a top-of-the-table shoot-out in Group C at Tokyo 2020 after both teams were victorious on Thursday.

In a tough preliminary round pool, both Spain and Slovenia have two wins from two to reach the quarter-finals heading into an intriguing match-up.

With perennial Olympic champions the United States looking a little ordinary, the two nations will fancy their chances of breakthrough golds.

Their latest exploits ensured Sunday's game will attract plenty of attention, considering it could open the door to a potentially easier route through the knockout rounds.

RUBIO INSPIRES SPAIN AGAIN

Spain reinforced their status as the team to beat as they eased past Argentina, the opponents they also defeated in the 2019 FIBA Basketball World Cup final.

Ricky Rubio was the MVP at that event, leading the champions with 20 points in the final, and he was highly influential once more in Tokyo on Thursday.

The Minnesota Timberwolves guard had 26 points – 13 in each half – with 83 per cent three-point shooting in an 81-71 success.

It was all painfully familiar for Argentina, as Nicolas Laprovittola explained: "We know Spain, we know how they play, we know Ricky Rubio is the key."

With Doncic up next, Spain coach Sergio Scariolo added: "We are 2-0. We beat a very strong team, so we take it and we move forward." Doncic is 15-0 in Slovenia colours in all competitions.

'IT'S NOT ONLY LUKA... THAT TEAM CAN HOOP!'

Doncic is undoubtedly Slovenia's player to watch, having added to his 48-point Olympic debut against Argentina with 25 points, seven rebounds, seven assists, two blocks and two steals in a 116-81 demolition of hosts Japan.

But Slovenia – described by Japan coach Julio Lamas as "a very complete team with one amazing player" – have more to them than the 22-year-old alone.

Zoran Dragic weighed in with 24 points, while Vlatko Cancar shot five of five from the field – including three of three from deep – for 16. Klemen Prepelic added 12 in 20 minutes off the bench.

"It's not only Luka," said the Washington Wizards' Rui Hachimura, whose 34 points were in vain. "That team has guys who can actually hoop. There's a lot of guys who can score."

Turning their focus towards the Spain game, Slovenia coach Aleksander Sekulic said: "We want to play our game and we're going to prepare and we're going to be ready for them.

"We have a great coaching staff; they're really doing an amazing job. We want to play our style, our game, and also make Spain think about us."

ROJA REVENGE AS WOMEN SINK SERBIA

It was double delight for Spain on Thursday as their women claimed an eye-catching win over Serbia, the new European champions.

Spain had won back-to-back EuroBasket Women titles prior to co-hosting this year's event, where they were beaten by Serbia in the quarter-finals.

Serbia went on to take the championship and named a strong team again for the Games, but Spain fought back in Group A.

Alba Torrens put up 25 points and Astou Ndour added 20 along with nine rebounds in an 85-70 win that puts them top of the pool.

"We know they badly wanted this revenge from Valencia," said Serbia coach Marina Maljkovic, while Jelena Brooks added: "Knowing Spain and what they came here to do because of the Eurobasket, we knew they were going to punish our mistakes twice as bad as Canada did [in the opening game]."

Canada, meanwhile, recorded a 74-53 triumph over South Korea early in the day.
