Roncero was not particularly despondent despite the setback however.

He said: “In the first half, we made childish mistakes. To win was not the main thing but we were looking forward to giving a greater identity to the team.”

Felipe Contepomi, who played at centre despite an outstanding display against Ireland earlier this year at fly-half, was also unconcerned, adding: “We need more time playing together. We shouldn’t be too desperate over this.”

Federico Serra believed a more measured approach could pay dividends.

He said: “I think we need more patience in some situations. In the second half we changed our plan and that’s a good thing.

“There are several things to correct. We made quite a lot of mistakes in defence during the first half. In these kind of Tests we cannot give away those types of errors.”

Argentina’s final warm-up game before the World Cup in France comes next Saturday when they meet a Belgium XV in Brussels.

One player who will hope to take part is centre Martin Gaitan, who suffered a “cardiac problem” after the Wales game.

He fainted in the dressing room and was rushed to hospital where it was discovered one of his arteries was dilated.
