In their last two tests with the World Champions the Pumas have managed to keep their defences intact for over a hour, while against the Wallabies a 19-6 lead became a 19-23 final scoreline as the Wallabies managed to overrun the Argentineans at Skilled Stadium in the Gold Coast.
Phelan said ultimately there was but one objective against the All Blacks.
"Saturday's goal will be to avoid the drain of the final minutes," Phelan said.
However Phelan was happy with how the team was growing through what was arguably their toughest ever rugby tournament.
"Our objective is to improve match by match. In defence the players are full of confidence, we're getting better and as a consequence the results will follow," said Phelan.
"To play this tournament implies effort rather than pressure. I single out the valour, commitment, heart and passion of the team.
Impressive Pumas centre Santiago Fernandez gave his team the plan they needed to follow to beat the All Blacks for the first time.
"We have to play a perfect game, given they are the world champions and the best team in the world," Fernandez said.
"We have to play tough defence and take advantage of the few chances we get. They don't make many mistakes, and we have to be ready to capitalise when they do."
