Ireland scrum-half Conor Murray's says Ireland are "under no illusions" about the challenge they face against Argentina tomorrow.
The Pumas have looked very powerful so far in the tournament and ran the All Blacks very close in their 26-16 loss last month.
The Munster scrum half says the Irish squad are very of Argentina's quality.
He said: "We're a very honest group of players, we know how good Argentina are, and how good they can be.
"At the same time we know if we perform well we are in with a shout of winning again."
