The All Blacks are in Dublin with revenge on their minds.
Steve Hansen's men became the first All Black team to ever lose to Ireland two weeks ago, and the Irish are bracing for an almighty backlash.
Ireland's historic win in Chicago would have done wonders for their confidence and diluted some of the All Blacks' unbeatable aura.
However the Irish know a black storm will hit Dublin on Sunday morning, with their New Zealand born coach Joe Schmidt conceding they've "poked the bear".
"I don't think you get a tougher test because they are unhappy obviously. When you win 18 in a row and you get into that habit you're not happy to lose that and they want to get straight back on track and with the talent they have it's going to be incredibly tough to stop them doing that."
Schmidt said that Ireland will have to exceed their benchmark if they are to beat the All Blacks for a second straight time.
Ireland's New Zealand born centre Jared Payne agreed and said the All Blacks will be a stronger and more ruthless beast than the one they encountered in America.
"Every game they play they've said it there's pressure on them to win they're expected by the New Zealand public back home to win every game so they're going to leave no stone unturned in their preparation and they're going to come out and put us to the sword."
Before the loss in Chicago the All Blacks had conquered all before them this year and assistant coach Ian Foster said that slap in the face has given the side a cold blooded focus.
"These are great weeks, there's an edge in the air and we love preparing for big test matches. Coming to Dublin and preparing to play Ireland here is always pretty special for us it's a fantastic stadium the supporters are amazing and I guess what's happened in Chicago has added more seasoning to it hasn't it."
The New Zealand prop Wyatt Crockett knows nothing would mean more to the Irish than beating the World Champions on home soil.
"They've got the monkey off their back and for them the ultimate would be able to back it up, I think that's a sign of a really good team so there's pressure on us (All Blacks) to perform."
And perform is exactly what lock Brodie Retallick said they plan on doing.
"It's going to be a big game for us after Chicago and coming here and playing in Dublin is always huge. We're disappointed that we let ourselves down as a team in Chicago and we want to come here and rectify that so we're going to take control of the physical battle and nail our execution and then just play our game."
Hansen believes his players were distracted in Chicago and he's confident they'll hit back in the Dublin rematch.
Hansen said baseball's world series and the fairytale Chicago Cubs triumph may have engaged too much of his squad's attention and he's taking no chances in Dublin after picking his strongest possible side.
"What's exciting about this week is we're playing an opposition two weeks after being beaten by them and we're going to learn a lot about ourselves. We've got no excuses for not having the right attitude because the loss has certainly sorted that out. Now it's about are we good enough to beat them."
The 2009 Springboks were the last team to beat the All Blacks in two consecutive tests and even former Ireland captain Brian O'Driscoll said it will be a tough feat to emulate.
"It'll be tight again, you know it took us 111 years to get the first one so to expect two on the bounce is a push but it's not beyond the bounds of possibility."
O'Driscoll believes if the hosts are to make more history on Sunday, they'll need more than a little luck of the Irish.
