Argentina have made two changes to their lineup, at halfback and fullback, for Saturday's Rugby Championship test against Australia.
The Pumas will use the same forward pack that strongly tested New Zealand before going down 21-5 last weekend. But Martin Landajo has been named at halfback ahead of Nicolas Vergallo and Lucas Gonzalez Amorosino at fullback, replacing Martin Rodriguez.
Lock and vice-captain Patricio Albacete has been named to play his 50th test, lining up against Nathan Sharpe who will captain Australia in his 109th test appearance.
Argentina has played three matches so far in the inaugural four-nation Rugby Championship for a loss and a draw against South Africa and a loss to New Zealand. Australia beat South Africa on Saturday after two losses to New Zealand.
