SAM Warburton believes a fervent Friday night against Ireland in Cardiff will ensure Wales' Six Nations doesn't fizzle out after their title hopes were ended in Edinburgh, writes Chris Kirwan.

Saturday's 29-13 hammering at the hands of Scotland means that Rob Howley's men are no longer in contention to take the crown from champions England.

Flanker Warburton, who had another strong game at Murrayfield, says that disappointing their big backing in the Scottish capital will fuel their desire to strike back against the Irish even if the chance of silverware has gone.

"You can't win a Championship losing two games so we know that's gone," said Warburton, a Grand Slam winner in 2012 and title winner the following year.

"For the rest of the campaign we are playing for pride and there were so many Welsh fans that went to Scotland, we noticed that on the bus on the way in and in the stadium.

"We appreciate that they spend a lot of time and money coming to watch us play so putting in a good performance for them in two weeks at home is what they deserve from us."

Warburton says their week off will be a painful one as they dissect a horror show in Edinburgh in which a pointless second half saw a 13-9 half-time lead turn into a 29-13 loss.

"We need to have a good, honest debrief of the game and we've been doing that over the last couple of weeks with players putting their hands up when they've made mistakes," he said.

"We need to do that to learn and need to be harsh on each other. A good breakdown of that game is what is needed and all we can do is try and improve.

"There is no greater motivation than playing at a packed Principality Stadium."

Wales let plenty of chances slip through their grasp against Scotland and Warburton wants a more ruthless streak a week on Friday against an Ireland side fresh from wins against Italy and France.

"Our accuracy in the Scottish 22 let us down on a few occasions," said Warburton. "We let them off the hook and have to be more ruthless; we needed to come away with points but didn't and that was our downfall."
