Richie Mo'unga and Beauden Barrett started together for the All Blacks throughout the World Cup.

The playmaking combination of Beauden Barrett and Richie Mo'unga were among four All Blacks selected in a Rugby World Cup XV based on stats and no Springboks featured despite them becoming world champions for a third time.

Centre Anton Lienert-Brown and prop Joe Moody were also included in Opta's team of the tournament after South Africa won the World Cup in Japan, beating England 32-12 in the final in Yokohama last Saturday.

Opta said the line-up was based on a unique scoring system. Scores were based on a per 80 minutes rate and players needed minimum of 320 minutes in the tournament to make the cut, with props required to play 240.

According to Opta's scoring, Beauden Barrett at fullback achieved the highest score of any player after making the most carries (86), averaging the most carries (17) and third most metres (92) per 80 minutes of anyone eligible.

Barrett and Mo'unga first started a test together against South Africa in July, which finished a 16-16 draw, and the jury is out as to whether their combination will continue in the international game with All Blacks coach Steve Hansen standing down.

Runners-up England had three players, Samoa two, Fiji and Wales one each, but there were no South Africans after the Springboks matched New Zealand's record of three global titles.

The All Blacks finished a disappointing campaign with a 40-17 win over Wales in the bronze final but they surrendered their world title.

Of the others All Blacks included, Lienert-Brown was at second five-eighth having beat the most defenders (28) and gained the most metres (284) of any centre.

Mo'unga beat the most defenders (17), gained the most metres (184) and made the most offloads (7) of any first five-eighth.

Moody made the most tackles of any prop (49) and his tackle success rate was 96 per cent. He was one of only two props, along with Ireland's Tadgh Furlong, who scored more than one try and didn't concede a single scrum penalty.
