Cruden is expected to be named on the bench for the Pumas, despite some quarters feeling that Dan Carter's 'understudy' could start against the South Americans, and the young prodigy expects the Argentineans backs to attack.
The Chiefs playmaker was arguably the player of the Super Rugby season, and said that the Pumas threat came from their experience in the Northern Hemisphere.
"They've got quality backs who play all around Europe," said Cruden.
"We know that it does start with their forwards but they do have the firepower out wide to really threaten teams.
Cruden played a limited part against the Pumas in the Rugby World Cup, just before his starring role against the Wallabies, before he too fell to the first five-eighth curse for the All Blacks at the quadrennial tournament - but in 2012 he has risen to become a world class player according to most.
He said that they had to be aware of a growing Pumas back offensive division, especially with some teaching from Sir Graham Henry.
"We're going to have to be aware of that," Cruden said.
"They boys are going to have to study them very closely so we're not caught unaware come Saturday night."
"The Argentineans will try and take it up the middle through their forwards and then probably throw the ball out wide and unleash the backs."
