Ireland coach Declan Kidney described the seven-try rout of feeble Argentina at Aviva Stadium as the stuff of dreams.
The Irish secured their place among the second tier of seeds for the 2015 World Cup draw on Monday week with a record 46-24 triumph that saw Jonathan Sexton and Tommy Bow score two tries each.
"You never in your wildest dreams think you'll score that number of tries against Argentina," Kidney said. "If things click then this team is well capable of doing that. Today was one of the good days."
He added: "We didn't get too despondent after the defeat by South Africa two weeks ago and we won't be too disappointed following today.
"This result makes it a whole lot easier to go to training the next time we meet.
"If I say it was the complete performance I'll be out of a job! There's always things to be done."
Ulster winger Craig Gilroy produced a remarkable Test debut, tormenting Argentina's defence throughout and finishing with a wonderful try.
The 21-year-old was also involved in the build up to three other tries and Kidney admitted the squad's younger brigade had lifted the spirits.
"I've been saying for the last two weeks they've been a pleasure to work with," he said.
"The enthusiasm of the young lads who've come in - not just Craig but some of the others who didn't play - has been infectious. We talked about having a go at it and that paid off. We picked off a few good tries and that confidence flowed through the team."
