Argentina head coach Michael Cheika said on Thursday his much-changed outfit to face Chile in the Rugby World Cup this weekend can prove him a point.
Australian Cheika has made 11 changes from the victory over Samoa for Saturday's South American derby in Nantes.
Cheika has handed starts to the experienced five of hooker Agustin Creevy, No 8 Facundo Isa, scrum-half Tomas Cubelli, fly-half Nicolas Sanchez and winger Juan Imhoff.
They are all aged 30 or older with centre Jeronimo de la Fuente, who turned 32 in February, captaining the side.
Cheika's Pumas need to beat Los Condores, the lowest ranked side in the competition, to keep their hopes of a place in the quarterfinals alive.
"This team deserves to play in the World Cup, they have the chance to show what they can do," Cheika told reporters.
"It's a good team to play a very important World Cup match," he added.
Creevy becomes just the second Argentina player to 18 World Cup matches, after former Pumas head coach and hooker Mario Ledesma.
Sanchez makes his 100th test appearance, with Creevy the only other person to do so for the side.
Argentina finish their group campaign against Japan on October 8.
Chile are making their first appearance at a World Cup but have conceded 156 points in their opening three Pool D games.
