The 2007 World Cup saw Argentina announce themselves as an established force on the world rugby stage. Their impressive display, seeing them reach the semi finals before being defeated by eventual champions South Africa made the world sit up and pay attention. 4 years on, their World Cup was less spectacular, but equally as telling of their rise in the Rugby world and they will next year embark on their first Four Nations campaign, joining the Southern Hemisphere giants of Australia, New Zealand and South Africa in a revamp of the Tri Nations.
