Millennium Stadium visitors Ireland stand between Ruddock's team and a first RBS 6 Nations title.

A Wales victory on Saturday would also see them end a 27-year wait to taste Grand Slam success, with the Triple Crown proving another notable attraction.

Ireland, though, can still win the championship, provided they topple Wales by a minimum of 13-points and holders France do not embark on a half-century scoring spree against Italy in Rome.

Eddie O'Sullivan's men also have the added incentive of achieving back-to-back Triple Crowns, which merely confirms Ruddock's assessment that Ireland are Wales' most dangerous championship opponents this season.

Wales have not beaten Ireland in Cardiff since 1983, but Ruddock has vowed there will be no let-up from the unrelenting pace and intensity that has left opponents - and spectators - gasping.

There is no secret that our game has been based around a high tempo. We try to keep the ball in play and use our dangerous runners behind, he said.

I've got no worries about Ireland knowing that's our approach, because we made it clear to England and everyone else. How Ireland react is how Ireland react, so we will have to wait and see.

I think the modern game now demands that you go out and play in that way, Ruddock added.

Once you stop playing, like we did (against Scotland) in Edinburgh, and the other team gets hold of the ball and starts coming at you, it is very difficult to get out of that trend and seize the initiative back.
