Sexton, who admits they have to get on the right side of match day referee Wayne Barnes with whom he says they have had problems in the past, says the Irish have to execute their plan on how to beat the All Blacks to perfection.
"We've had it on our radar for a while, definitely".
Ireland is ranked No. 2, and has a chance to be No. 1 for the first time.
That record will be something he will be keen to improve upon and he makes no secret of how you can not treat the world champions just like any other game. Will Addison stepped in to make his first start and didn't let Ireland down, but Ireland will want to restore Ringrose with Bundee Aki. It has been two years since we've played them last but there has been a lot of changeover from our team.
The 33-year-old flyhalf - who orchestrated Ireland's historic victory over the All Blacks in Chicago in 2016 - believes if they seized their chance they could claim they are the number one team in the world.More news: Redskins' lack of lead change is first time in National Football League since 1954
"All those things so it wasn't just one thing that sort of led.they (Argentina ) are a good side as well".
"They've all been tough games, close games and they don't come along too often the way the seasons are structured now".
"I am not saying that to cause any stirring", Hansen added.
Nevertheless, Ireland coach Joe Schmidt said following last weekend's 28-17 win at home to Argentina that Murray, one of the world's leading scrum-halves, could still make a shock return against the All Blacks at Dublin's Lansdowne Road on Saturday.
Given Murray's lack of game-time - now sidelined for over five months - throwing him in for the biggest test of the year could be risky with rust and fitness potential issues.More news: Palace releases two stunning family photos to mark Prince Charles' birthday
After conducting their video review session at the Kildare base this morning, Schmidt's Ireland will return to the training paddock this afternoon as they gear up for the much-anticipated Test against Steve Hansen's side [KO 7pm, RTÉ2, Channel 4]. Then they score again.
"So, yeah, they really expose you when you're loose with the ball and so everything is a bit more important this week".
"They'll be better for that experience as well".
"That showed just before half-time when they're 15-0 down and 10 minutes to go and they managed to get 10 points".More news: Athenahealth fetches $5.7B cash buyout offer
