Los Pumas tweak backline for Wallabies clash

TEAM ANNOUNCEMENT: Argentina have made four changes to their team to take on Australia in their second Rugby Championship clash after losing the first last weekend as the Wallabies stormed back late in the game.

Argentina's Australian coach Michael Cheika has made three backline switches. He also brought in Thomas Gallo for Nahuel Tetaz Chaparro at loosehead in the front of the scrum for the test in San Juan on Saturday.

Gonzalo Bertranou replaces Tomas Cubelli at scrumhalf as Cheika sought to reprise the winning combination with Santiago Carreras at halfback from last month's 2-1 test series success over Scotland.

Matias Moroni will replace Matias Orlando at centre and there is a switch on the wings as Emiliano Boffelli moves to the right in place of Santiago Cordero, to allow Juan Imhoff to play on the left.

"We've tried to give everyone a chance in training in the week to show who, within the strategy for the game on Saturday, is ready for the game. Some have earned the opportunity from training and with others it might be a little bit tactical," Cheika said.

"For example, Bertranou was very sharp in training with a good understanding of the tactics. It's a strong combination we have at halfback and he wins his place to show what he can do on match day."

Cheika said Argentina would be looking to improve on multiple fronts in their second meeting with the Wallabies in a week.

"It's about improving all things, in the scrum, maul, line outs and rucks so that we can be competitive in every game," he added.
