The side knows it is in for a tough test when it takes on the All Blacks in a World Cup quarterfinal at Eden Park tomorrow night.
Argentina is at the longest of odds. If it was a horse race, the All Blacks are Phar Lap while the Pumas are the nag, slow out of the gates and running with three legs.
Argentina coach Santiago Phelan said the All Blacks had a very good squad and were a very difficult team to play against.
The focus for his side was to play as well as it possibly could.
"It is going to be a hard, challenging game where we are playing against the best team in the world. We have been growing match by match and we want to put on the best performance we possibly can," he said.
Argentina has suffered some bad injuries throughout its campaign but will field the same side which beat Scotland two weeks ago, except at No 8, where Leonardo Senatore replaces the injured Juan Martin Fernandez Lobbe.
Argentina captain Felipe Contepomi said the All Blacks were much better than the Pumas but for 80 minutes his side had to play as well as possible and be competitive.
"We are just focusing on what we want to do and try and ensure things are done well. But in sport anyone can win," Contepomi said.
His team will have to play the perfect game and rely on the All Blacks to have an off day.
In 13 tests between the sides, Argentina has never won, claiming one draw - in 1985 - and the last time the teams met was more than five years ago when the All Blacks won 24-19, in Buenos Aires.
Contepomi said the Pumas had got close in the past but that was when they played at home with 40,000 cheering supporters behind them. Playing the All Blacks at Eden Park in front of a New Zealand crowd was a different story.
Contepomi thanked the supporters who had travelled far to back his team and also the New Zealanders who had dressed up and got behind Argentina.
Contepomi has the chance to bring up an individual milestone, needing five more points to pass Hugo Porta's record for Argentina of 590 points.
Hooker Mario Ledesma will play his 18th game in the World Cup, equalling the mark setby a hooker, held by Frenchman Raphael Ibanez.
English prop Jason Leonard holds the overall record with 22 World Cup games.
