Argentina are on a roll having beaten Australia and South Africa in the past 12 months and captain Agustin Creevy insists the Pumas have "no limits" at the Rugby World Cup.
With Ireland reeling from injuries to key players, Argentina can sense an upset in the quarter-final at Cardiff's Millennium Stadium on Sunday.
Argentina last reached the semi-finals in 2007 when they beat Ireland on the way in the pool stage.
They also beat them in 1999 in a play-off for the quarter-finals.
Twelve months ago, Argentina beat the Wallabies 21-17 in Mendoza.
It was the last straw in a troubled reign and Wallabies coach Ewen Mackenzie was gone within two weeks.
One month before coming to the World Cup they defeated South Africa for the first time - 37-25 in Durban - forcing Springboks coach Heyneke Meyer to apologise to the nation.
The Pumas world ranking has gone up in a year from 12 to six, above England and France.
"This team has no limits," the 30-year-old Creevy declared.
"We have made mistakes, we have problems with nerves. But when we are confident, the team plays.
"In the quarter-finals, the team will be hungry, they can overcome those mistakes and we will be triumphant.
"We can reach the top - the semi-finals, the final, be world champions."
Creevy has taken delight in being captain since 2012, but his rugby career has had highs and lows.
He made his Test debut in 2005 against Japan as a flanker and secured a contract with French Top 14 side Biarritz.
After barely getting a game with Biarritz, Creevy suffered injuries and fell out of the Pumas reckoning until coach at the time Santiago Phelan suggested he switch to hooker.
Creevy went back to Argentina and fought his way back into the national side in his new position.
Now an established leader, he has since played with Clermont and Montpellier in France and Worcester in the English second division.
From next year he will be part of the new Buenos Aires team that will compete in the southern hemisphere's Super Rugby championship.
