Ireland wing Simon Zebo said the team's primary objective ahead of the fixture against France will be to eliminate the errors that crept into their game last weekend.
Ireland emerged unscathed with a 16-9 victory over Italy at Olympic Stadium but Zebo insists that France will not allow Ireland to get away with playing the way they did.
Both Ireland and France have already qualified for the knockout phase of the competition but the outcome of Sunday's match will have a significant impact on who they play in the last eight.
"Silly offloading, errors and knock-ons and things contributed to a bad flow in our attack and just didn't allow us to gain any momentum against the Italians," said Zebo on Wednesday.
"So we'll have to correct that this weekend because if the game does open up we'll have to be able to offload the ball and keep the continuity a lot better than we did last week".
For Ireland, momentum will be a critical factor this weekend, especially against a physical French team that will look to stifle that momentum early on.
"We just couldn't get a rhythm going against Italy, so we've got to make sure we gain a better flow against France," explained the Ireland wing.
"This will be a very physical game I'd say, it will come down to small margins, the little errors will be costly – but if it opens up, then all the better.
"I think we've an extremely talented pack that will give us momentum hopefully, and a great backline to run off it. We've all the confidence in our own team to mix it with them if it gets loose. But we'll still just make sure we do everything in preparation to be as ready as we can become this weekend."
