Argentina playing with a panache that will test Ireland’s defence to the limit

Argentina. It’s simple really, isn’t it? The Pumas have their powerhouse pack, are not afraid to use it and, oh yes, they’re Ireland’s World Cup nemesis.

Yet the Irish management’s reference points for Sunday’s World Cup quarter-final show an Argentina side coached by Daniel Hourcade very different from the standard perceptions and much improved on the second-string outfit they faced in a hard-fought two-Test tour in June 2014.

It is clear from talking to coaches and players this week Argentina’s landmark victory over South Africa in Durban this summer and their strong showing in an opening pool defeat to New Zealand four weeks ago are the yardsticks by which Ireland will judge the Pumas.
