The lineout, the scrum, the breakdown.
Both teams agree - it’s up front where tonight’s clash between England and the All Blacks will be won.
But World Cup winner Will Greenwood has a different view .
"It’s all about the kicking game," Greenwood old Newshub.
"Controlling territory, being secure when the ball is booted your way, exiting from restarts, and when you’re under pressure.
Make sure you stick it into the stands, and once it’s in the stand you can regroup and go. I think the kicking game absolutely holds the key to winning this game.
It’s the reason behind Eddie Jones’ decision to recall first-five George Ford, and move Owen Farrell into the 12 jersey - two playmakers tasked with nullifying the All Blacks’ most potent attacking weapon.
"He’s trying to keep Beauden pinned… look after the back field… stay away from being an attacking threat. And we’re gonna put you in the corners and force you to kick yourself."
England’s selections have left Barrett in no doubt about what to expect at Yokohama Stadium tonight.
"We guessed if they wanted to kick more, they’d play Farrell and George Ford," said Barrett.
Greenwood admits his prediction for the game has been fluctuating wildly.
"For three hours, I think we can, then for six hours, I think we can’t."
"We get one intercept, one loose ball, we rattle the scoreboard, we get in front… you guys will get nervous, because you always do."
