Ireland won their quarter-final place at the World Cup, but only after a strong challenge from Italy.
They've now qualified for the last 8 of the Rugby Union World Cup.
Ireland will face fellow quarter-finalists France in Sunday's Pool D decider at the Millennium Stadium.
Ireland boss Joe Schmidt said: "That game was exactly what we expected.
"We have been allowed to cruise through the first two games and it was a shock to the system to come against a tier one side who needed to win to stay in the tournament.
"France are another level up - we will have to raise our game again. We will work on that this week and hopefully come up with the goods."
- Ireland have now won 20 of their last 21 games against Italy
- Keith Earls scored his eighth Rugby World Cup try, and now stands alone as Ireland's top try scorer in the tournament's history
- Ireland won 10 out of 10 line-outs in this game and are the only team in the RWC yet to lose a line-out on their own throw (35/35)
