Juan Pablo Socino will make his Rugby World Cup debut on Sunday as Argentina make 11 changes to their starting XV to face Namibia.

The centre comes into Daniel Hourcade's side for the Pool C match in Leicester as the Pumas look to finish their knockout stage preparations with a third win of the tournament.

Only Guido Petti, Pablo Matera, Martin Landajo and Matias Moroni retain their places in the starting line-up against the African minnows, with the latter switching from outside centre to right wing.

Landajo takes the armband for the sixth time for the Pumas, while experienced duo Juan Martin Hernandez and Horacio Agulla return at fly-half and left wing respectively.

Meanwhile, Namibia have also switched 11 of their side that were narrowly beaten by Georgia on Wednesday – a result that earned them a first World Cup point in their history.

Coach Phil Davies is without captain Jacques Burger for the clash after he suffered a concussion against Georgia, the forward having since announced his retirement.

Back row Rohan Kitshoff will lead the side in Burger's absence, with only Torsten van Jaarsveld, Tjiuee Uanivi, Theuns Kotze and Chrysander Botha retaining their places.
