Former Wales full-back Shane Howarth believes scrum-half Rhys Webb has been the catalyst for much of Wales' good play during the autumn Test series.
Webb's half-back partner Dan Biggar was man of the match in Wales' 12-6 win over South Africa on Saturday.
But Howarth says Biggar was helped hugely by Webb as Wales beat the Springboks for just the second time.
"I really like Rhys Webb, there's something about him, he's really put his hand up," Howarth told Scrum V.
"The reason Dan Biggar is getting the time he's getting is that Webb is so lively around set pieces and the ruck, so defences have to hold on.
"And if they don't he's gone, as he showed against Australia with his dummy-go.
"So when you've got someone like that allowing you the time... it makes it a heck of a lot easier for a 10.
"With those two, the combination they've got at the moment, I really like it... and it's a combination at club rugby as well [for the Ospreys] so it can only benefit Wales."
While picking out the half-backs for particular praise New Zealand-born Howarth, who won 19 Wales caps between 1998-2000, is also enthusiastic about a growing sense of adventure in Wales' play.
"What I really like is Wales are starting to be a bit more expansive, I think they have to," Howarth said.
"You're not going to win a World Cup... just going through power, you've got to be able to adapt your game."
Howarth added: "They've got the pack that can handle most teams, what they need to do now is be more creative.
"If you're going to win the World Cup you've got to beat two southern hemisphere sides, probably in a row, so let's put that into perspective - Wales have had one win [over a Sanzar side] in the autumn series."
