Argentina will have to be "perfect" if they want any chance of beating New Zealand, says their captain Agustin Creevy.
It's a big ask, but Creevy believes his team is capable of such a performance despite the fact that no Argentina side has ever manage to beat the All Blacks.
"That is why it is such a big challenge for us," Creevy told the New Zealand Herald.
"But we believe that if we do things really well, if we have the perfect game, we can beat them even knowing they are one of the best teams in the world."
Argentina's recent success againt South Africa no doubt plays a role in their new found confidence, even if the gulf in class between the Springboks and the All Blacks is the biggest it's been in more than a decade.
After coming close to beating the Boks for the second time in their own back yard, los Pumas let a 10-point lead slip in the Test in Nelspruit, going from a commanding 23-13 lead to a 30-23 defeat.
However, they came good a week later in Salta, Santiago Gonzalez Iglesias slotting a 78th minute penalty for a famous 26-24 win.
"We were not very happy as we didn't close out that [first] Test, Creevy said.
"But when we beat them [Boks] in Salta, it showed to the team that we can get a good result after having a disappointing result the week before."
They also need only look back at recent their most encounter with the All Blacks in New Zealand to find further encouragement. Last July's loss in Christchurch did expose a major All Black weakness – an inability to defend lineout drives.
Creevy isn't getting carried away with that success 14 months ago, despite seeing it as an important weapon if done correctly.
"We have to have a good lineout before we can make a good maul. We know that that gave us good results in Christchurch last year, but first we must have a good lineout."
