Argentina coach Daniel Hourcade has revamped his starting XV for their final pool game against Namibia in Leicester.
Hourcade made 11 personnel changes and one positional switch to the team that defeated Tonga 45-16. Lock Guido Petty, flank Pablo Matera, scrumhalf Martín Landajo and utility back Matias Moroni are the only players retained.
Having done so on five previous occassions, Landajo will take over the captaincy for Sunday's match.
Moroni moves from outside centre to left wing, and is joined in the back three by Lucas Gonzalez Amorosino and Horacio Agulla.
Juan Pablo Socino and Santiago Iglesias are the new midfield combination, with Juan Martín Hernández and Landajo paired as the halfbacks.
Up front, Javier Ortega Desio and Facundo Isa join Matera in the loose trio, Matias Alemanno comes in at No 5 lock, while Juan Pablo Orlandi, Julian Montoya and Lucas Noguera form the front row.
Argentina – 15 Lucas Gonzalez Amorosino, 14 Matias Moroni, 13 Santiago Iglesias, 12 Juan Pablo Socino, 11 Horacio Agulla, 10 Juan Martín Hernández, 9 Martín Landajo (c), 8 Facundo Isa, 7 Javier Ortega Desio, 6 Pablo Matera, 5 Matias Alemanno, 4 Guido Petti, 3 Juan Pablo Orlandi, 2 Julian Montoya, 1 Lucas Noguera.
