Matt Dawson has suggested that Argentina have shown the "consistency of performance" to be a success in international rugby over many years.
The Pumas reached the last four of the Rugby World Cup after beating Ireland 43-20 at the Millennium Stadium.
However, Dawson has suggested that the level of talent of in the Argentina ranks shows that they are becoming a force on the global stage.
He told BBC Sport: "The consistency of performance is always key to success, and I also believe Argentina have some real game-breakers - players such as (Joaquin) Tuculet, (Juan) Imhoff, (Santiago) Cordero.
"They have probably learned from playing in Europe and playing in the Rugby Championship.
"There's talk of them getting a Super 15 franchise too, so this is just the beginning for Argentina."
Argentina will meet Australia for a place in the final.
