Welsh confidence is high following mighty autumn displays, albeit both in defeat, against New Zealand and South Africa, while a much-changed England are without injured World Cup stars like Jonny Wilkinson, Mike Tindall, Will Greenwood and Richard Hill.

After Wales, England take on France at Twickenham before tackling tournament favourites Ireland in Dublin, so a defeat this weekend could derail their campaign before it leaves base camp.

''We could have happily done with being at home in the first match, instead of being in Wales,'' said Leicester forward Rowntree, who will win his 49th cap.

''We have huge respect for Wales. We watched them in the autumn internationals, and they were highly impressive.

''The power in their side is more spread out, and the forwards are very mobile. You have to look at the threat from the forwards now, and names like Gavin Henson in the backs spring to mind. He is a very exciting player.

''You look at the Six Nations this season and it is wide open,'' he added.

''We have a major task on our plate going down to Wales, and we know what we are up against.''
