Ireland failed to take their chances in a narrow Six Nations defeat to France on Sunday, according to captain Iain Henderson.
It was a first win in Dublin for Les Bleus since 2011, and they looked like they might run away with it after Damian Penaud scored their second try in the 54th minute.
Ireland, to their credit, battled back and scored the next 10 points to set up a potential grandstand finish at the Aviva Stadium.
But it wasn't to be as a late attack petered out and referee Luke Pearce called a halt after France turned it over and kicked to touch.
But Henderson, speaking to Virgin Media Sport, said the game was there for the taking.
"Massively frustrating," was his initial reaction. "The biggest thing for me was that we had the opportunities to go and do it.
"When you're not taking those opportunities, especially at home, you're not where you need to be, to be beating teams like France.
"We've go to go away, review what we've been doing... we've got a two-week break until our next game. A week to get away, refresh our heads (and) make sure we're really tuned in for fixing those mistakes.
"When they go down to 14 men you have to capitalise in this game. You've got to punish people for having ill-discipline.
"We just didn't do that - that was our opportunity to get up (ahead) in the game. We ended up two points down.
"Even a penalty in there, or a try, and that's a different looking second half."
The defeat means that Ireland have lost their first two games in the Six Nations for the first time ever, with the competition only having five teams when it last happened back in 1998.
Head coach Andy Farrell echoed the sentiments of his captain after the match.
"I thought it was an evenly contested game, certainly within that first half," he began.
"We managed the game pretty well and I think quite of number of things within our grasp were going to plan.
"It was unlucky... well, we had a chance in the first half and probably should have gone into the sheds at half-time in the lead.
"The third quarter, I thought we just lost our way a little bit in terms of game management and I suppose that got them back in the game.
"We'd an opportunity to score a try (in the first half) and (if) we carried the ball another five metres, nice and square, knock their defenders off, I think we score that try.
"That's the one glaring opportunity but that's what test match rugby is all about."
