Nelson Mandela's 90th birthday celebration fixture between Argentina and South Africa has more than the odd sub-plot.

As the Pumas endeavour to force their way into the Tri-Nations, the high profile clash will go along way to proving whether Santiago Phelan's side have the calibre to match the southern hemisphere giants.

Juan Martin Hernandez, Gonzalo Tiesi and Tomas de Vedia are unavailable and they are currently in off-season, so a titanic battle against the world champions is far from ideal, especially with the majority currently enjoying the sunshine.

Argentina squad:

Forwards: Horacio Agulla, Patricio Albacete, Rimas Alvarez, Miguel Avramovic, Lucas Borges, Rafael Carballo, Manuel Carizza, Felipe Contepomi, Martin Durand, Juan Fernandez Lobbe, Alvaro Galindo, Juan Francisco Gomez, Pablo Henn.

Backs: Alfredo Lalanne, Pedro Ledesma, Mario Ledesma, Juan Manuel Leguizamon, Esteban Lozada, Federico Martin Aramburu, Jose Nez Piossek, Rodrigo Roncero, Hernan Senillosa, Bernardo Stortoni, Benjamín Urdapilleta, Nicolas Vergallo, Alberto Vernet Basualdo.
