SCOTLAND V WALES (Saturday KO 5pm) WALES will be on a mission when they take on Scotland at Murrayfield in Saturday’s Six Nations clash – stop Dan Parks and his support runners, writes Robin Davey.

That is the warning from openside flanker Sam Warburton who finds himself lining up directly against his Cardiff Blues teammate in the Scottish stronghold.

“A lot of us play with Dan, he’s the captain’s pick, but we’ve said he’s got defensive weaknesses and we will aim to capitalise on that by playing one of the best ball carriers in Europe (Jamie Roberts),” warned Warburton.

“I hope me and Dan (Lydiate) work together and get some hits on their midfield. It’s not so much the No 10 but the players playing off him as well.

“He was brilliant last year for Scotland and he’s been good for the Blues, he’s got a great kicking game and we must try to put pressure on him.

“We mustn’t allow him to take the ball to the line and then take it on from there, then it will limit their options.”

Warburton admits Wales are facing a real hurdle at Murrayfield now if they are to end their winless run stretching to eight games and says they must cut down on their mistakes.

“Losing to England means it’s uphill now especially with three away games to come,” he said.

“But Saturday’s game is definitely winnable so it’s not all doom and gloom.

“It will be a fast game which I’ll enjoy especially compared to the England match which was one of the toughest matches I’ve played in.

“But we back our fitness levels and their tight five will probably tire before we do, especially if we can spread the ball.

“We’ve identified the same mistakes we’re making every game,” he said. “It’s those top two inches, we know we’re physically there, now we’ve got to make sure we’re switched on mentally.

“We’ve got to get the game plan right and do what we’ve been told because we didn’t switch on against England so we’ve got to make sure we do it this weekend, trust ourselves then the tries will come.

“I like playing in front of big crowds, that doesn’t make me nervous it’s my own expectations that do that.”

Coach Warren Gatland has told his forwards what he wants from them.

“We have talked about better execution and accuracy but largely we want the same again from the forwards with Ryan Jones coming back into the mix as well,” he said. “Ryan has shown true character after some stebacks in terms of selection and playing in different areas of the pack, and he has come out on top.”

And forwards coach Robin McBryde added, “We struggled for field position in the first half last week which meant we didn’t attack in the way we would have liked but we are hoping to put that right this week.

“We know we are under pressure but the pressure we put on ourselves is more than enough and there is no-one working harder than us to put it right.”
