Argentina coach Michael Cheika on Monday announced his squad for the Rugby World Cup in France, cutting experienced wingers Santiago Cordero and Bautista Delguy.
Cheika opted for a team made up of 18 forwards and 15 backs, with hooker Julián Montoya as captain.
The Australian included full-back Martín Bogado, who made his debut last Saturday against South Africa, and winger Rodrigo Isgró, from Argentina's sevens set-up.
Cheika said the decision to omit 29-year-old Cordero was "very difficult," but he decided to go with four centres instead.
Matías Orlando, Tomás Albornoz, Lucas Paulos, Sebastián Cancelliere and Lucio Sordoni were also left out.
"We are going to the World Cup with the experience of Nico Sánchez, who has already been in three World Cups," said Cheika, referring to the fly-half.
He said he had picked a "balanced squad," some of whom could play several positions.
"The goal is always to go for the maximum, not to settle for the quarter finals or semi-finals. We want to reach October 28 [the finals] and win," he said.
Their last warm-up match for the Pumas will be against Spain in Madrid on August 26.
Argentina are in Pool D of the World Cup, and start their campaign on September 9 against 2003 winners England.
They will then face Samoa on September 22, Chile on September 30 and Japan on October 8.
