Forward Allister Hogg says Scotland's back-row must significantly raise their game if they are to compete with New Zealand's celebrated breakaway trio. The All-Blacks are out to complete a Grand Slam against the Home Nations.
"We had a better breakdown last week against Argentina and we need to target that during training this week," Hogg said after Scotland beat Samoa 18-11.
"It's not so much a worry now. I think we've realised what the problem was and it was a bit of a wake-up call."
The physicality of the Samoan forwards gave Hogg, Jason White and Simon Taylor an uncomfortable afternoon.
Meanwhile, the rucking of Graham Henry's back row has been pivotal in New Zealand's victories.

Big-hitting blindside Jerry Collins, rapidly-maturing number eight Rodney So'oialo - immense against England on Saturday - and imperious open-side Richie McCaw have dominated in the loose during their tour of the British Isles.
McCaw missed the win at Twickenham and Hogg said: "I don't know how bad McCaw's head knock was - hopefully it might keep him out another week.
"But, having said that, it's why you play, to challenge yourself against someone like that.
"There are pros and cons like anything else, but I suppose it would be nice to play against him.
"I'll just try to do my bit. Jason and Simon know what they are doing, so you don't have to worry about what they're doing.
"That's what's good about our combination in the back row.
"I don't think you'll see the same problem this week. We'll address it and hopefully it won't happen again.
"It wasn't so much a case of not committing enough players to rucks, it's basically more a need to stay strong over the ball, seal the ball and protect it."
Hogg, who scored his fifth try for Scotland against Samoa following a textbook rolling maul from the forwards, is well aware of the awesome power and pace he will face on Saturday.
"They're by far and away the best team in the world at the moment," he said.
"England pushed them close at the weekend and showed what to do against them.
"We need to get in their faces, put their skills under pressure and hopefully they'll make mistakes."
Meanwhile, Scotland winger Rory Lamont was undergoing post-concussion assessments following the head injury he sustained in the victory over Samoa.
But team doctor James Robson insisted that the tests were merely "routine".
