SAM Warburton will face Australia at the Millennium Stadium tomorrow admitting he is sick of losing to the big three from the southern hemisphere.
The Wales captain has suffered ten defeats from as many matches against Australia, New Zealand and South Africa.
"It frustrates me," said Warburton. "Scotland have beaten Australia and they've done well against South Africa. Beating these sides is doable, that's what frustrates me.
"It is getting to the stage where you think enough is enough — we have to beat them."
At 24, Warburton can count himself lucky that he hasn't yet endured the kind of misery that has come the way of Ryan Jones, Mike Phillips and Gethin Jenkins, stalwarts in the Wales side who must have grown accustomed to their annual beatings at the hands of the world's best.
Jenkins has just one win to show from 31 outings for Wales and the Lions against the big three, while Phillips has one from 22 and Ryan Jones has a win and a draw from 24 outings against the Sanzar mob.
"I've only been involved for three or four years and it's already getting on my nerves, this whole southern-hemisphere scalp business," said Warburton.
"I don't know how the players feel who've been around ten years or so, like Mike and Ryan. But I'm definitely feeling frustrated and I think the rest of the squad feel the same."
Warburton faced Richie McCaw last week, and this weekend goes in with the second best openside in the world in David Pocock, who has returned to Australia's side after injury.
The No. 7 duel is a contest within a contest, with the outcome likely to go a long way to determining which side comes out on top.
Wales coach Warren Gatland said: "There will be two quality, world-class No. 7s out there and another one on the bench (Justin Tipuric). Pocock's a different player to McCaw, a different threat in the way he plays.
"I think you need a genuine No. 7 to compete at the breakdown because in international rugby it's so fierce."
