Pumas coach Santiago Phelan's made half a dozen changes to his side for Sunday's Rugby Championship test against the All Blacks in Argentina.
Most come in the backs with Phelan naming a new halfback, midfield combination and right winger from the side that lost to Australia by one point.
It's a similar side that played New Zealand earlier this month and All Blacks assistant coach Ian Foster told Radiosport that Argentina will be tough to beat.
"I've got no doubt about that. I think when we walked off the field in Hamilton, we'd played a big, physical test match," he said.
"We probably weren't that happy with our game, but a lot of that was because they stopped us. It's a big challenge.''
Lock Patricio Albacete and hooker Eusebio Guinazu come into the pack. Halfback Martin Landajo, and winger Lucas Gonzalez Amorosino return along with midfielders Santiago Fernandez and Marcelo Bosch.
