Argentina captain Felipe Contepomi conceded the Pumas will have to produce the "perfect game" to stand any chance of beating New Zealand in Sunday's Rugby World Cup quarter-final.
The bookies have given New Zealand a 27-point start on the Pumas and Contepomi admitted his men will be playing for pride first. He is barely considering the chance of an upset.
"Over 80 minutes we have to play the game and put up a performance we can be proud of," said the former Leinster fly-half, who is five points short of setting a new Argentina points record. "We have to try to do the perfect game and if we prepare our tactics well, then luck may go our way."
He added: "We can make that luck for ourselves, but we are up against the best team in the world."
Exeter wing Gonzalo Camacho is one of four players recalled to the Pumas side to face the All Blacks, along with full-back Martin Rodriguez, lock Manuel Carizza and veteran prop Rodrigo Roncero.
With the exception of number eight Leonardo Senatore, who has taken over from the injured Juan Martin Fernandez Lobbe, it is the same Argentina team that started their victory over Scotland.
