WALES shocked the rugby world when they almost toppled eventual World Cup winners England in November's quarter-final in Brisbane.

They have got to go out with exactly the same attitude on Saturday, says experienced openside flanker Martyn Williams.

By a strange coincidence he meets with a similar fate as in Australia - he has been left out as coach Steve Hansen goes for the same big back row of skipper Colin Charvis, Dafydd Jones and Jonathan Thomas to try to match England there.

"We've got nothing to lose so we've got to try to play like we did in the World Cup," said Williams. "That has gone now and it counts for nothing, but it gives us confidence and shows we can play against them. We've got a bit of self belief this time."

Wales haven't won at Twickenham since 1988 and Williams admits it might now be a psychological barrier. He also believes the Wales coaching uproar has helped the team.

"It is psychological especially at Twickenham, we haven't won there for a while," he admitted. "There's such a big build-up, but we can handle it better now, we've been together for a while and Ireland have shown they're not invincible.

"Normally the build-up to the England game lasts a fortnight, but with the coaching thing the game has been secondary. That has been a good thing as it has taken it away from us.

"Everyone wants to play against England and beat them, especially being world champions. That gives it a bit of an edge and it's still Wales' biggest game.

"They have got bags of experience, they want to play again and they won't be phased. They're all world class players and they know what to expect."

Williams is surprised England didn't recall Neil Back, whom he describes as 'the heart and soul of the side.'

"They could struggle without players like Back, Johnson and Wilkinson, but Ireland was probably the worst thing that could have happened to us.

"But it'll be a great atmosphere and you've got to feed off it, more so this time because the crowd will be desperate for a win."
