Argentina have retained the squad that stunned South Africa at the weekend except injured Jeronimo De la Fuente and added six players for a Test rematch in Buenos Aires Saturday.

A rib injury rules centre De la Fuente out of a game that offers the Pumas a chance to prove that a historic 37-25 Rugby Championship triumph in Durban two days ago was not a fluke.

It was the first Argentine victory in 20 Tests against South Africa and their first away win in the southern hemisphere championship after 10 losses since debuting three seasons ago.

Argentina took 26 players to South Africa last week and coach Daniel Hourcade has expanded the squad to 31 for the rematch with the Springboks at the 50,000-capacity Estadio Jose Amalfitani.

The six additions are full-back Santiago Cordero, centre Matias Moroni, fly-half Nicolas Sanchez and loose forwards Javier Ortega Desio, Juan Martin Fernandez Lobbe and Facundo Isa.  

"While we are thrilled at our famous victory in Durban, the focus has already switched to the rematch," flanker Pablo Matera said Monday before flying from Johannesburg to Buenos Aires.

"It is going to be extremely tough in Buenos Aires because the Springboks are hurting and they will throw everything at us."

Asked what was the secret behind the sensational success in Durban, Matera responded: "Self belief. We were convinced that we would win."

Defeat caused two-time world champions South Africa to drop three places on the official international rankings to fifth while Argentina remained eighth.

The Buenos Aires Test will be the last for Argentina and South Africa before the September 18 kick-off of the Rugby World Cup in England.

South Africa are in Pool B with Japan, Samoa, Scotland and the United States and Argentina are in Pool C with title-holders New Zealand, Georgia, Namibia and Tonga.
