Whitelock wary of Wallabies lineout threat

All Blacks lock Sam Whitelock is not underestimating the Wallabies particularly the lineout threat posed by Adam Coleman and Rory Arnold.

Ahead of Saturday's Rugby Championship and Bledisloe Cup opener in Sydney, Whitelock acknowledged Coleman had shown his competitiveness last season.

"Both of those guys have been really physical with the way they carry the ball around the breakdown," he told the All Blacks' official website. 

"They've been aggressive.

"That's how they're going to play and we've got to make sue as a team we're ready for that and we have a plan." 

Coleman has already laid down a gauntlet by saying the Wallabies believed they had the ability to end 14 years without the Bledisloe Cup by beating the All Blacks this year.

Whitelock said there had been no problem making the adjustment to Test rugby again after four weeks of Super Rugby play in which time his Crusaders side secured their eighth, and his first, title.

Getting back into camp with the players last week in Auckland had got them focused on the Bledisloe Cup game straight away.
