Ireland centre Gordon D'Arcy has branded his side's last-gasp 24-22 defeat to the All Blacks on Sunday as a career low point.
The 33-year-old, who was recalled after missing Ireland's loss to Australia, believes he has had his last chance to beat New Zealand as he is in the twilight of his Test career.
"I don't think we have them in the next year and a half, so it probably was my last go at them," he said.
"It's a pretty horrific one to take, I was broken by it I think.
"I've been involved in other games like that, but this is probably a low point in my career."
But despite the narrow defeat, D'Arcy wants Ireland to use their impressive performance against the All Blacks as a stepping stone towards success in the Six Nations under new head coach Joe Schmidt.
"If we don't build on that and it doesn't become the base for the Six Nations, then what did we achieve? Nothing," he added .
"We talk a lot about wanting to move forward, but sometimes we get in our own way and we pull out one performance and we're perceived as not being consistent enough.
"There is definitely a level of progression from these three autumn games, but this is only a positive if after five games in the Six Nations then we walk away from that with five consistent performances, and hopefully a trophy."
