Wales defence coach Shaun Edwards says a return of one win from the autumn clashes with South Africa, New Zealand and Australia would be “fantastic”.

Wales have only beaten South Africa once, have nine wins in 27 games over Australia and not beaten NZ since 1953.

“Statistically looking at history you’d have to say percentage-wise one victory would be fantastic,” he said.

“But it’s not really for us to think too much far ahead to the Australia game, to the New Zealand game.”

The Wasps head coach says Wales will do everything in their power to earn that all-important victory against a southern hemisphere power when they meet the Springboks on Saturday at the Millennium Stadium. He also believes taking on the world champions is the sport’s most challenging task.

Edwards said: “We’re playing the world champions in our own back yard and we’re going to have all the passionate Welsh fans behind us and we’re going to give it everything we’ve got.

“It’s the ultimate challenge playing against the world champions.” Edwards says to be in with a chance of beating a team as physical as John Smit’s side Wales must achieve excellence in defence, set-piece play and turn-overs.

“This team (South Africa) is physical, but I think they also add a lot of skill to their game.

“Their off-loading game is excellent and they’ve also got the X-factor. “You are looking at (Ruan) Pienaar possibly playing at 10, who’s a magnificent rugby player and he could be a supertstar in that position, who knows?

“We realise we did very well in the Six Nations, but I think we all know this is a step up level from that.

“For us to compete with these teams we’re going to have to up our ante and I thought we finished our Six Nations fantastically well against France.

“But I think if we’re to beat these teams we’ll have to improve again on that. We’re very determined to do that.”

Edwards acknowledges the 2011 World Cup is a “long way off” and that there is a gradual build-up to the tournament.

“But this is the next step on that journey,” he added.
