Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
Speaking to the media on Wednesday, experienced Italian prop Martin Castrogiovanni says the squad is working hard to recover from their disappointing outing against England last weekend.
"After a first half like that, I don't think anyone can play worse than we did," he said.
"We have to start from there and keep going up. That's what we're working on."
The big question is can Italy recover quickly to challenge an Irish side that delighted their fans with a 30-21 home win over France.
"We are used to this, in the sense that we are not a team that has won too much," he added.
"It's hard but it means you have to work even harder to improve.
"Things will be even more difficult on Sunday because Ireland are playing better than England.
"But we are here to win. We don't want to put on a good show, we want to win."
