Argentina have been hit by serious injuries ahead of the tournament but are still tipped to put the cat among the pigeons in Pool D - the widely-acknowledged 'Group of Death'.
The Pumas will open the tournament against France at the Stade de France under a cloud after losing center Martin Gaitan because of heart trouble and full-back Jose Maria Nunez Piossek due to a thigh injury.
But Marcelo Loffreda's side have an excellent record against the French and, ranked sixth in the world, are more than capable of causing an upset against Ireland.
Their strength has traditionally been in their ferocious forward pack, known for its mighty scrummaging, but Loffreda has managed to add more potency in the backs with the development of the likes of wing Ignacio Corleto and new prodigy fly-half Federico Todeschini guided by veteran scrum-half Agustin Pichot.
If they can upset the Irish and finish second in the group then a likely quarter-final clash with New Zealand awaits - the top placer will most likely face Scotland or Italy in the last eight. E-mail to a friend
