Argentina scrum-half Martin Landajo has suggested that former New Zealand head coach Graham Henry has helped mastermind a new brand of attacking rugby from the Pumas.
The South Americans hired Henry, who guided the All Blacks to Rugby World Cup glory in 2011, as a consultant in 2012.
However, Landajo has claimed that Henry's input has had a lasting impression on Argentina.
He told reporters: "Graham Henry came to help us and we've tried to play that rugby since then. Now with Daniel Hourcade we've developed stronger rugby. When Graham arrived I remember he said that we needed to create more tries.
"We had a great defence, one of the best in the world, but we didn't attack much, and he said it was impossible to win games like that. He told us we could defend for 80 minutes if we wanted, but that we wouldn't win.
"So he tried to change our minds, he did it, it wasn't easy but now with Daniel he wants to follow the same line, he likes to play and to attack. So we've tried to change to an attacking game. We won't let our defence slip but we've improved a lot."
The Pumas face Ireland in the quarter-finals at the Millennium Stadium on Sunday.
