Wales backs coach Rob Howley says fly-half Dan Biggar was "outstanding" in their 12-6 win against South Africa.
And former Wales scrum-half Howley says Biggar and fellow Ospreys half-back Rhys Webb are "unique" heading into the 2015 Six Nations.
Biggar was man-of-the-match against the Springboks as Wales beat them for only the second time.
"Dan Biggar was outstanding today. I think he's matured as a number 10," said ex-Wales captain Howley.
"His communication off the field, his diligence, his work ethic has been fantastic and he's defended particularly well and I'm sure Shaun [Edwards, defence coach] will be really pleased with how he's defended.
"But the way he's navigated us around the park today has been outstanding.
"And I think we've got a unique half-back [pairing] there. They're both very young and they can grow together and they can lead us on into the Six Nations."
Wales went into Saturday's game with a record of one win in 27 games against major southern hemisphere nations.
Howley put the win down to greater composure than South Africa as Wales ended that miserable run six years to the day since beating Australia.
In their other autumn Tests, Wales pushed world champions New Zealand hard before conceding three late tries to lose 34-16, were narrowly beaten 33-28 by Australia and were also 17-13 winners against Fiji.
"We probably showed composure more times than maybe South Africa through our team," said Howley.
"I think that it's an outstanding group of players.
"You look back over the last six years at how close we've come against Australia, New Zealand, South Africa.
"It's composure, being clinical when you need to."
Wales coach Warren Gatland hopes his side's win over the Springboks can herald a successful start to their 2015 Six Nations campaign.
The European tournament kicks off with 2015 World Cup hosts England's visit to Cardiff's Millennium Stadium on Friday, 6 February.
