Ireland coach Andy Farrell says they can't afford to get carried away with Saturday's win over South Africa.
A 13-8 win over the defending champions in Paris on Saturday means that his side have one foot in the quarter finals.
They have the weekend off this week, before facing Scotland on Saturday week.
Farrell says they can't afford to look past the Scots.
"Honestly, we're not concentrating on that [the quarter finals] at all. We're just trying to concentrate on ourselves, and wherever that takes us, we'll deal with that as we go.
"Knowing that it is probably going to be either the All Blacks or France, they're two fantastic teams that we'll concentrate on further down the track."
On the performance at the Stade de France, that saw Ireland run out five point winners over the Springboks in an intense 80 minutes, Farrell says his team were excellent.
"That was a proper game, a traditional game, which had everything. There were ebbs and flows, ups and downs, and how we managed to stay on point mentally I thought was fantastic.
"The game was never going to be perfect, first half I thought we had the rub of the green as far as field position is concerned, perhaps we didn't capitalise on that. And it was certainly roles reversed then in the second half.
"How we kept our heads, getting those couple of penalties right at the end when it really mattered was the real plus side of our performance.
Ireland struggled in the line out early on, and Farrell says that was down to the excellence of their opponents.
"That's the quality of the Springboks, and that's the quality of the opposition that's going to be coming the more we're able to stay in this competition and keep moving on.
"Keeping ourselves on track mentally and staying at it was absolutely the key. Our discipline, certainly in the second half, was very good in the line out.
"It was roles reversed wasn't it? In regards to the penalty - the early engage from South Africa, and the penalty we got on the line to kick the goal.
"Again, we stayed at it mentally, and rolled with the punches, but came out strong the other side as well."
Ireland have a weekend off this week, before facing Scotland in their final pool game on October 7th.
