Argentina, with injuries to four leading players, have made nine changes for the Rugby World Cup third-place play-off against South Africa at Olympic Park on Friday.
Coach Daniel Hourcade named a team on Wednesday, captained by flyhalf Nicolas Sanchez, with a future ring about it, especially in midfield. Old hands Horacio Agulla and Juan Manuel Leguizamon also return.
Lucas Gonzalez Amorosino, an early replacement for wing Juan Imhoff during Argentina's bruising 29-15 semi-final defeat by Australia at Twickenham on Sunday, comes in at fullback to replace Joaquin Tuculet, who suffered a shoulder injury.
Agulla, a veteran of the 2007 bronze medal team in what is surely his last Pumas test, stands in for wing Imhoff who suffered a knock to his head in the first half on Sunday.
Also out are hooker Agustin Creevy and veteran centres Juan Martin Hernandez and Marcelo Bosch with Matias Moroni back for a youthful centre partnership with Jeronimo de la Fuente.
Julian Montoya replaces captain Creevy in the front row while Leguizamon, another of the 2007 vintage, returns at number eight after being out of action since suffering an injury during the pool stage nearly four weeks ago.
Agulla and flanker Juan Fernandez Lobbe will be facing South Africa for the second time at a World Cup having been part of the team that lost their semi-final in France in 2007.
Meanwhile, Lock Victor Matfield will bring down the curtain on his international career when he captains a strong South Africa side for the match.
The veteran of 126 internationals is one of two changes to the starting line-up from the team that lost their semi-final to New Zealand 20-18 last weekend as coach Heyneke Meyer seeks to add the tiniest piece of gloss to a campaign that has otherwise been a major disappointment.
The 38-year-old Matfield, who has already said he will retire - for the second time - from international rugby after this tournament, replaces the impressive Lood de Jager, who drops to the bench.
The other change sees Ruan Pienaar start at scrumhalf for the first time since the stunning 34-32 defeat to Japan in the Springboks' tournament opener, with the influential Fourie du Preez not considered because of injury.
Third-choice number nine Rudy Paige, who made his debut in the 64-0 rout of the USA in their final pool match, comes onto the bench.
Fly-half Pat Lambie will win his 50th cap if he gets game-time off the bench.
