Righto, time to load up the team bus and head home at the end of a gruelling afternoon of rugby.

We can sit here and be flippant about France, but he is under massive pressure. I just worry about the team he is picking.

Whisper it quietly, but there is the whiff of a young Dan Carter about George Ford.
His natural instinct is invariably the right option and the England fly-half chooses exactly right as he hangs onto the ball, selling Rob Harley a dummy, to open up a path to the try line, which he has the pace to take.
A straightforward kick to add the extras.

Righto, time to load up the team bus and head home at the end of a gruelling afternoon of rugby.
After a good night's sleep though we will be back to bring you France's trip over to Italy. As Sir Clive says, it could get real messy.

"Philippe Saint-Andre is under massive pressure. People ask me if I miss the job and while the highs are great, no-one can understand what he is going through now. It is not a good place to be. We can sit here and be flippant about France, but he is under massive pressure. I just worry about the team he is picking. His head is in a noose and, if he loses tomorrow, I'm not sure he will coach France against England."

We are heading for a heck of a climax next weekend, but the Six Nations has a habit of serving up last-day drama.
In 2007, a last-minute try from Elvis Vermeulen against Scotland gave France a 46-19 win and took them past the 24-point winning margin they needed to overtake Ireland in the race for the title.
If next weekend can match that we might be talking about the best Six Nations tournament ever...

Whisper it quietly, but there is the whiff of a young Dan Carter about George Ford.
His natural instinct is invariably the right option and the England fly-half chooses exactly right as he hangs onto the ball, selling Rob Harley a dummy, to open up a path to the try line, which he has the pace to take.
A straightforward kick to add the extras.

1990. 2000. 2006. 2008. But especially 1990.
Scotland's wins over England are the stuff of legend, but the common denominators tend to be Murrayfield and/or pelting rain.
Scotland have a winning record over England in Edinburgh, but have won on only four of 36 visits to Twickenham.
The last time was 1983.

"We are planning for a backlash from Scotland, and they should be planning on one from us."

BBC Wales Sport's Dafydd Pritchard at the Millennium Stadium
After a breathless start, the Millennium Stadium fell silent for a moment as Wales prop Samson Lee was taken off injured.
Until then, it had felt like a firework display here - only that it has been brutal tackles rather than pyrotechnics creating the spectacle.
Each ferocious hit has been met with cries of "ooh" and "aah" as Welsh and Irish players crash into each other like dodgems on the pitch. This is not for the faint-hearted.

BBC Sport's Ben Dirs on Twitter: "I'm not sure anyone expected this, Ireland just haven't fathomed Wales' variety of attack. They've slept walked into a threshing machine."

Wales 12-3 Ireland
Wales have the ball back in hand but Alun Wyn Jones bites off more than he can chew, charging into the entire Ireland back row.
Jamie Heaslip and Sean O'Brien gobble him up, freezing his forward momentum and keeping him hanging off the floor to earn the turnover.
Penalty
Wales 12-3 Ireland - Sexton
That is more like normal service.
Johnny Sexton finds the sweet spot of the instep, hammering clean off the tee to split the sticks.

Wales 12-0 Ireland
Another chance for Johnny Sexton. Scott Baldwin to blame for Wales with a needless high tackle near halfway.
Missed penalty
Wales 12-0 Ireland
Ireland have been on the rough side of Wayne Barnes' whistle so far, but they have a break there with George North pinged for hanging on to his man after the tackle.
It is a tricky chance, off on the angle, but Johnny Sexton won't be happy with the tugged effort.
He has had a slow start .

"This will not be good for Wales, Samson Lee is crucial to the scrum. It is a big ask for his replacement Aaron Jarvis and it also ends the momentum Wales had built up. This is a big blow for Wales, a big blow. And a certain Adam Jones has retired. Adam, put your pint down and get back on the treadmill..."

Penalty
Wales 12-0 Ireland - Leigh Halfpenny
Wales started like a train against England and came a cropper thanks to a sluggish second half.
They are putting plenty of points in the bank while they are hot this afternoon.

Wales 9-0 Ireland
Wales' Samson Lee will not play any further part in this match. The prop is getting oxygen on the pitch after a serious looking leg injury.
Skipper Sam Warburton calls his troops, including Lee's replacement Aaron Jarvis, in for a pep talk.
Play will restart with a Wales penalty 30-odd metres out. Leigh Halfpenny will take a pop at goal. And you would not bet against him...

Wales 9-0 Ireland
Ireland are rattled. Johnny Sexton muffs his kick-off, clearing the touchline on the full to mocking cheers from the crowd.
That part of the game has been one of Ireland's best under Joe Schmidt.
Penalty
Wales 9-0 Ireland - Halfpenny
Leigh Halfpenny is hitting the back fence at the driving range today.
A boomer of a kick from bang on halfway has more than enough distance, clearing the crossbar with plenty to spare.
Jonathan Davies is already talking about points difference for next weekend...

"Wales have to take the opportunities if they are on out wide. Ireland defend narrow at times - Wales must take the chance if it is on."
Post update
Wales 6-0 Ireland
Leigh Halfpenny is showing his full repertoire. After the pin-point place kicking and a sky-scraping claim in an aerial contest with Conor Murray, he claims a mark with an astonishing diving take, just inches off the deck.
What a player.

Phillip Matthews

"It's all coming from the tactical kicking by Wales, Ireland just can't deal with it at the moment. These are probably the two best kick-chase teams in the championship, so there isn't going to be an advantage for Ireland as they have had in other games."
Penalty
Wales 6-0 Ireland - Halfpenny
With his side under heavy pressure, Ireland blind-side flanker Peter O'Mahony tries to be a hero, nibbling for the ball after chopping down his man in the tackle.
Wayne Barnes pings him right in front and Leigh Halfpenny could kick that one in his carpet slippers.
Post update
Wales 3-0 Ireland
There is a bit of ambition about Wales this afternoon. Twice it goes wide, Liam Williams is pinned the first time, but Jonathan Davies shoves off a tackler and strides on to the Ireland 22.
The crowd are demanding points. Five preferably.

"We all knew how crucial the ruck area was going to be - they just can't be isolated. Wales are trying to move the disciplined Irish defence around."
Penalty
Wales 3-0 Ireland - Halfpenny
Off comes the scrum cap, up go the flags.
In between is one of the most reliable kicking actions in the game.
First blood to the hosts.
Post update
Wales 0-0 Ireland
Wales are getting the heavy artillery rumbling.
First Taulupe Faletau and then James Roberts go barrelling into contact. Ireland thrown hefty defence in the way, but they have not rolled clear.
A very kickable penalty for Leigh Halfpenny...

Kick-off
Wales 0-0 Ireland
Wayne Barnes of England is in charge. He cheekily asks Dan Biggar which way he is going to kick off.
Plum down the centre must have been the answer. And Wales regain possession....

Time for the anthems.
Ireland's Call is all very nice, but it stands no chance on the decibel meter.
Hen Wlad Fy Nhadau is so loud that the crowd effect microphones are fizzing.

BBC Sport Wales' Dafydd Pritchard at the Millennium Stadium
Wales have a history of making Ireland feel at home in Cardiff. Since 1983, Wales have only twice won on their own turf against the Irish.
The hosts are in hospitable mood today as well, with the Welsh choir treating the Millennium Stadium crowd to a rendition of the Irish folk ballad 'Fields of Athenry'.
It's not long, however, before those dulcet tones make way for the heartier roars of home favourite 'Bread of Heaven'.

As Paul O'Connell leads out Ireland, you have just enough time to check out the comic performance of the tournament so far.
In this BBC Wales video, Mike Phillips nominates Colin Farrell to play him in a film and himself as the best-dressed player in the Wales dressing room. His pet hate? "Arrogant people."
All totally deadpan.

There is plenty of history to go at in the Six Nations, but you don't have to delve too far back in the books to find some fizz and feist to Wales v Ireland.
Warren Gatland admitted back in 2009 that that two sides don't get on and that was before Gatland dumped Brian O'Driscoll for the final Lions Test in Australia.
This could get tasty.
Post update
Wales have not been winning too many artistic merit marks either. There is plenty of bosh and not too many surprises in the way their hefty backline run the ball.
Forwards coach Robin McBryde is unapologetic.
"Are supporters likely to see open rugby? I am not too sure about that," he said.
"It's going to be an arm-wrestle for 80 minutes."
At least the kids are all right.
Savour this delicious score from Wales under-20s in their own meeting with Ireland last night. You are unlikely to see two successive back-of-the-hand offloads at any point in today's game.
