DAN Biggar says his Wales team-mates have nothing to fear as they take on South Africa in the Rugby World Cup quarter final today.

Having beaten the Springboks in the autumn, the fly-half believes his team can produce the goods again against the two-time world champions to book a place in their second successive World Cup semi final.

He said: "We've got absolutely no fear.

"Obviously we've got a huge amount of respect for them, the players they've got and what they've achieved, but whoever we were playing in the quarters we wouldn't fear.

"Hopefully the country can get behind us as they have been over the last three or four weeks which has been awesome and let's all try and be positive.

"We're in a World Cup quarter final with a huge chance of getting through to a semi.

"We should've won the second test out in South Africa last summer and then we had a great win at the Millennium Stadium last autumn.

"Out of the Southern Hemisphere teams, recently we've got the best record against them.

"There's no denying they will bring their a-game and it will be a huge task for us to stop that.

"We'll probably go in as underdogs, but we're looking forward to that."

South Africa's gameplan is unlikely to be too subtle, and Biggar is ready for the test.

"They're always strong up front, they'll kick well, they'll have a good set piece, their rolling maul will be good so we'll have to limit the number of lineouts we give them," he said.

"We're expecting a physical game and they've been pretty impressive since their opening day defeat to Japan.

"It's going to be a huge match, a difficult game, but we're looking forward to it.

"The objective at the start of the tournament was to get out of the pool and we've done that so we've got to be positive and move on."

Looking back at last week's 15-6 loss to the Wallabies, the Osprey admitted the period Australia were down to 13 was pivotal.

 He said: "I think during that period we were held up over the line three times.

"I don't know if we could've kept the ball in the scrum for a little bit longer and potentially got a penalty try, but the game probably swung then.

"They went down the other end and kicked a penalty.

"Each decision was going for us in terms of penalties put a bit more pressure obviously on them, but on us as well.

"They defended it well and we definitely should've scored a try in that period.

"That's test match rugby.

"We score there and we probably go on to win the game and give ourselves a big lift.

"We're disappointed to have lost the test match, of course we are, but let's keep things in perspective.

"We've done well so far with everything surrounding us and we're in a World Cup quarter final.

"The boys are gagging for it."

Shaun Edwards had done his homework on Michael Cheika's men, and Wales used the choke tackle to great effect to slow the Wallabies' ball down.

"It was something we tried to work on in not only slowing their ball down on the floor, but also in the tackle by holding the ball up in the air for a few seconds," said Biggar.

"If we get a maul and a turnover from them then great, but we know we're slowing their ball down.

"The problem England had last week was that nobody was competing for the ball, Australia were getting free-flowing ball and Foley and Giteau were able to pull the strings quite effectively.

"It's something we spoke about during the week and it's pleasing we brought it into the game.

"We try and do that every week.

"We vary it every game and try and get boys like Tips [Justin Tipuric] and Warbs [Sam Warburton] on the ball and we've also got boys like Toby [Taulupe Faletau] and Alun Wyn [Jones] who can hold players up.

"We might try and mix it up because South Africa will present a different challenge with their physicality."

There were thousands of red shirts at Twickenham last week, and Biggar is hoping for more of the same from the Welsh supporters today.

He said:  "It was strange.

"It's the first time we've ever played at Twickenham as a neutral venue, which was good.

"It was a different atmosphere and the Welsh support was awesome as always.

"We're certainly going to need that next week, so fingers crossed they can give us a bit of help."
