Pumas v All Blacks: Everything you need to know

New Zealand take on Argentina in Buenos Aires on Saturday knowing that victory will be sufficient to wrap up a second successive Rugby Championship title.

The All Blacks have dominated the competition in 2017, sweeping all before them with four straight victories – only one of which did not include a bonus point.

If Argentina are to stop Steve Hansen's side from clinching the trophy in South America they will have to do something they have never done before - beat the reigning world champions.

Hansen had intended to use the trip to rest star playmaker Beauden Barrett, but the fly-half was a late call-up following the birth of Lima Sopoaga's first child.

Sam Whitelock and Brodie Retallick have been given a break, though, with Scott Barrett and Luke Romano forming a new partnership at lock.

"I think the boys who have stepped into those roles have done a fantastic job and we've got a team who's willing to put everything on the line," said All Blacks captain Kieran Read.

"Their team is well balanced. They've certainly got a team on paper that is aggressive, they'll attack us from anywhere with their backs.

"We've just got to be on our game. They're physically pretty good up front. If we're just off or not giving them the respect they deserve we could be in for a long day."

Argentina have added experience with the return of Juan Manuel Leguizamon – the number eight set to make his 80th Test appearance for the Pumas – and will be keen for a strong response after a 45-20 defeat in Australia last time out.

PRE-MATCH TALK

Daniel Hourcade (Pumas): "Playing the All Blacks always represents a special challenge because it means facing the best team in the world and that motivates you in a very special way."

Steve Hansen (All Blacks): "They're growing their game away from just one or two areas. They're trying to expand how they play and they're starting to get better at it and I think it'll be a really physical encounter."
