You could just see Josh Adams holding that width. It was definitely a pre-planned attack. George North is in plenty of space and he's dropped it on a sixpence has Dan Biggar. That's the experience and quality we were talking about pre-game.
Try George North, con Dan Biggar
Brilliant from Wales!
Anthony Watson wasn't even off the field when Dan Biggar booted a cross-field ball over his head into the arms of Josh Adams, who darted down the right before being felled just short.
Wales recycle it quickly and this time sting another kick towards the onrushing George North out left.
The wing sticks out an arm, gathers it in and saunters over unchallenged.
Biggar adds the extras.
Wales 3-0 England
And off Watson goes for 10 mins.
Wales 3-0 England
Great feet from and a slinky step from George Ford as he wriggles through a gap in the Welsh line, but somehow the ball pops up in the hands of a red shirt. Wales look to zip it left but England scramble.
They'll get another chance down the same side and this one is knocked on by Anthony Watson as the England man looks to wrap Hadleigh Parkes up.
We're going to the screen, could be trouble for Watson...
Wales 3-0 England
Dan Biggar wants to prove he can carry Wales in Gareth Anscombe's absence, and the fly-half has started well - he needs to be patched up after a blow to the nose, mind. Get the cotton wool out.
Half an hour in and it's Wales who hold a narrow lead in a tight warm-up game.
Wales 3-0 England

After a scoreless first half so far and Wales repeatedly deciding to go for tries and not penalties, the hosts finally relent.
And interestingly it is Dan Biggar and not Leigh Halfpenny doing the kicking at goal as he slots over the successful penalty.
Remember Wales go top of the world rankings if they win this game.
Wales 3-0 England

The strength of the Welsh game is the defensive set-up but at some point that will have to give.
Wales 3-0 England
Tut, tut. Joe Cokanasiga, not releasing the ball as England's attempt to hit back immediately comes to an end with the winger being penalised. Good work from the Welsh defence and that's greeted warmly by the Cardiff faithful.
Wales 3-0 England

Wales did well there keeping the ball. Maro Itoje came up with such a forceful tackle. Wales were very resilient keeping the ball and forcing three points.
Dan Biggar
No mistake from Dan Biggar from close range. Over it goes.
Wales 0-0 England
The Wales forwards roll off the side of every ruck, keeping it alive through 13 phase before England creep offside and this time Dan Biggar will go for the posts.
Wales 0-0 England

This doesn't look good for James Davies. The Scarlets flanker, making only his fourth appearance for Wales today, has been dogged by injuries in recent seasons.
And now he's been forced off by another. Josh Navidi, another playing his way back towards match fitness, is on in his place.
Wales 0-0 England
The first quarter of the match is gone.
These are the stats so far. Wales coughing up a lot of free ball so far.

This isn't what Warren Gatland wants to see.
It looks like James Davies took a knee to the head from Maro Itoje and he'll have to make way for a check up.
Josh Navidi comes on.
Wales 0-0 England
Former England centre Mike Tindall wants to see the officials enforce the rule over supporting your own bodyweight at the breakdown.
It is a jungle in there.

I think Alun Wyn had called for the three points but Biggar wasn't having any of that so Alun Wyn gave up and said 'go on then'.
Wales 0-0 England
England concede two penalties in quick succession, the second of which is inside their own 22. Dan Biggar doesn't fancy the sticks though, he wants the top prize...
Wales opt for the line-out and drive but England's pack is pretty formidable at the moment. They turn it over to earn the put in. Frustration for Wales.
Wales 0-0 England
If last weekend's Test had an almost exhibition feel to it, this has started out as real Six Nations-esque arm wrestle. Almost 20 minutes gone and no one has threatened to worry the scorers.

It's a game of chess at the moment. Both sides are feeling each other out and the inaccuracy is there for both teams.
