Declan Kidney says his inexperienced Ireland team will need to learn lessons from the defeat to South Africa in order to progress.
Ireland led 12-3 at half-time with four Jonathan Sexton penalties but failed to score after the break, while the visitors, through a Ruan Pienaar try and kicks from Pat Lambie, added 13 second-half points to claim the spoils.
“We have good players here now so we just need to learn from it, there’s a little bit of experience that we need as well too,” Kidney told RTÉ Sport.
“There’s a lot of inexperience there and I think a lot of them stood up and it’s about being able to do that week in, week out. We’ll have to see how guys prepare after this match and then pick the best team for next week.”
The defeat stretched Ireland’s winless run to five Tests but Kidney was eager not to focus on the negatives.
“It’s been a difficult fixture list but we've a lot of young players and new caps that came into it there and it’s all about being as positive as possible because we’re just at the start of a series now,” he said.

South Africa try-scorer Pienaar was thrilled to play his part as the Springboks roared back to beat Ireland.
The Ulster player said: "I think we had a terrible first half.
"Our kicking game wasn't that great. In the second half our forwards made a huge step up.
"We got a couple of good drives going, kept the ball and forced them to make errors.
"I'm very proud of the guys, especially in the second half."
Asked if there was any sense of concern that South Africa had managed just one try, Pienaar said on BBC2: "Not really.
"It's a hard place to come and play rugby. It's a good Irish team.
"To get just one try is the least of our concerns."
