Pumas skipper Felipe Contepomi knows Argentina will be in the fight of their lives when they meet the All Blacks in the Rugby World Cup quarter-finals.
Contepomi's Pumas tackle the tournament hosts at their Eden Park fortress on Sunday, where New Zealand, unbeaten for 17 years in Auckland, will be nothing less than overwhelming favourites.
Despite the size of the task facing his team, captain Contepomi is nevertheless confident Argentina, who have never beaten the All Blacks, are equipped to give a good account of themselves.
"We are playing against the best team in the world," said Contepomi, whose side reached the semi-finals of the last World Cup in France.
"We have been growing match-by-match and we hope to put up a performance we can be proud of and if that leads to a win then so much better.
"If both teams play at 100% then the odds will be against us but it is sport and anything can happen in that 80 minutes."
Coach Santiago Phelan echoed his captain's comments about the daunting prospect of attempting to contain the All Blacks.
"They have a very solid team with very few weak points," said Phelan.
"We will try to concentrate on trying to control the rhythm of the game to something we feel comfortable with."
In total there are four changes to the side from the one that defeated Georgia in the final pool game as Phelan largely reverts back to the team that stunned Scotland.
Leonardo Senatore, who replaced the injured Juan Martin Fernandez Lobbe during the dramatic victory over Scotland, will continue at number eight.
Prop Rodrigo Roncero has been passed fit after overcoming a groin injury.
He joins second row Manuel Carizza, winger Gonzalo Camacho and full-back Martin Rodriguez in returning to the starting line-up after all three were rested for their team's final pool match against Georgia.
Contepomi goes into the match needing five points to overtake Hugo Porto as Argentina's all-time leading points scorer.Argentina team:
