Argentina coach Santiago Phelan has made three changes to his squad for the second Test against England in Salta this weekend.
Perpignan lock Rimas Alvarez, Cordoba Athletic flanker Genaro Fessia and Clermont Auvergne hooker Mario Ledesma replace Mariano Sambucetti, Alejandro Abadie and Alvaro Tejada in the team that lost 37-15 to England at Old Trafford last Saturday.
Number eight Juan Manuel Leguizamon feels that his side must cut down on the number of fouls if they are to reverse last week’s result: "We have a chance for revenge and we must improve.
"It was a very tough match and we gave away too many fouls. The rivals know where the opponents' weak points are and force you to make those mistakes."
"We still have to keep training very hard. We must improve our image."
Former Argentina captain Agustin Pichot feels that good performances against England will help in their stated aim to join the 6 Nations.
"Important people have been talking a good game about supporting the Pumas but they don't seem to ever deliver,” he said.
“In Europe everybody – fans, union officials and players – used to say to my face how they would love to see the Pumas in the 6 Nations and that would be the ideal solution.
"But when it came to it last year and the IRB held a summit meeting on the subject not one of the Six Nations committees supported us in our request."
