By Country / Argentina

Who'd have thunk it, eh? One game could play such a crucial role for the next three years. Thanks to the IRB and their somewhat confusing qualification points system, Argentina's visit to Ireland might as well be a World Cup Final.

Ireland must win to secure their place in the second tier and have recalled Geordan 'maverick' Murphy at full-back and Jerry 'pit-bull' Flannery at hooker to bolster their chances.

Argentina need a win to guarantee a seedings spot and despite stuttered progression since Marcelo Loffreda's exit, Santiago Phelan's merry men are just 80 minutes away from avoiding the southern hemisphere triumverate in 2011.

Phelan has been forced into a number of changes, most notably at inside centre, where captain and local-boy, Felipe Contepomi misses out. Juan Martin Fernandez Lobbe takes over as skipper while Juan Manuel Leguizamon comes in at number eight.

Ireland haven't beaten the Pumas since 2004 but if there was a moment to end their drought (and that goes for crossing the try-line too) this wouldn't be an awful occasion.

Dax winger Lucas Borges has withdrawn from Argentina's squad for November's international series.

Pucara's Mauro Comuzzi has been called up as a replacement while Clermont Auvergne's Alejandro Campos completes the touring party.

It's been a bad week for Argentina boss Santiago Phelan with the news that star prop Rodrigo Roncero could miss the autumn internationals after being cited in Stade Francais' defeat by Toulouse.
