Skills coach Scott Johnson has admitted that Wales are bracing themselves for a bruising encounter on Saturday, but has warned that they won't fight fire with fire.

The Principality take on South Africa at the Millennium Stadium on Saturday in a game that promises fireworks on and off the field on Guy Fawkes night.

But while Johnson's knows that the Springboks will play the power game, using their bruising strengthn up front to control the game, Wales will adopt an altogether different approach.

He said: "It doesn't take a rocket scientist to work out the way they'll play against us.

"They'll come at us, and hard. They have a very talented, young, physical back row division and two quality locks and it'll be no different to what you saw in the tri-nations, and I'm sure our boys will be needing the ice packs after the game.

"It will be a physical confrontation but we are probably diametrically opposed to them in the way we play." Johnson added: "It will be good contrasting styles and I can't wait...bring them on. We'll play our way and they'll play theirs.

"They are a big physical side, and they dominate games and that is what they are very, very good at but we are not a massive side, but what we do have in our side is great skill and we intend to play to our strengths. "We've got some great kids in our side and when we get the ball we'll do it our way and let them worry about it."

Johnson is thrilled that Wales will play two of the World's finest rugby sides this Autumn and feels that if Mike Ruddock's side are to improve then they must play more games against the likes of the Springboks and All Blacks.

"It is great that we are playing South Africa and teams of this calibre and not avoiding the top nations. "The World Cup success of England was built on playing the top sides and having some victories but also having some failures and really knowing where you stand.

"Perhaps in the past there has been a reluctance to play the so called best sides."

Wales and Dragons star Michael Owen added: "I have seen that people are saying that two wins out of four would be a good return.

"But we are aiming to win all four. That has to be our attitude and there is a strong belief that it is possible." l Meanwhile, South Africa captain John Smit has been declared fit for this weekend's international against Wales in Cardiff.

Smit was initially doubtful for the match after a freak collision in training last week when midfielder De Wet Barry stood on his ankle.

But the skipper, who was on crutches last Friday, has made an unexpected recovery, and was seen running around the training field on Monday.

"It's a miracle really," Smit said. "I'm running fine and it's a whole let better."
