Rugby: All Blacks captain Ardie Savea places faith in rookie pair Quinn Tupaea, Tupou Vaa'i ahead of second Argentina clash

All Blacks captain Ardie Savea backing his side's inexperienced players to stand up and make the most of a rare start in Saturday's Rugby Championship clash against Argentina.

With just six days since last week's 39-0 victory over the same opposition on the Gold Coast, the All Blacks have been forced into wholesale changes to keep the team fresh for future matches.

Coach Ian Foster has made 11 changes to the starting XV for Saturday's match at Brisbane's Suncorp Stadium, including inexperienced midfielder Quinn Tupaea and lock Tupou Vaa'i.

Combined, Tupaea and Vaa'i have played less than 10 tests. Saturday's match will earn Tupaea his third test cap, while Vaa'i will play in his seventh match for the All Blacks.

But despite the rookie pair being handed crucial starting berths, captain Savea is confident they are up to the task of facing a physical Argentina side out for revenge.

"The boys know what's expected of them [in] doing their job," Savea says. "I just like to encourage in small ways and remind the boys that they're here for a reason.

"That's about it. I trust them to do their job and they're in this team for a reason.

"Even though they have less caps, it doesn't matter. Those boys are raring to go."

Savea is also anticipating an Argentina bounce-back, after they were kept scoreless on the Gold Coast.

Since the historic 25-15 loss to Argentina in Sydney last year, the All Blacks have beaten Los Pumas 38-0 and 39-0 in their two following encounters.

But that won't lead to any complacency from the All Blacks, who could go a long way towards securing the Rugby Championship title with another victory.

"For us, even though there have been changes, it's about backing that up," says Savea. "If we turn up thinking the same performance as last week will be enough, we're kidding ourselves.

"We know the Argie boys, they're a wounded beast. They're dangerous right now.

"If we don't turn up, it could be a long day."
