Who will take the honours?
Phil Vickery, Dafydd James and Adam Jones all predict a Wales win tomorrow. In fact, Mr. James is so confident that he gives us a specific score: 18-12 to Wales.
But he thinks Ireland will take the Six Nations title, and so does Phil Vickery.

Is it fair that Wales are criticised for playing such a structured game?
BBC SportCopyright: BBC Sport
I get frustrated looking in to Wales from the outside. I know what Warren Gatland is like, I know what Shaun Edwards is like and I know what Rob Howley is like. It's because of what they are like that people in Wales are able to say "come on , we've got a chance here."

Last year England were good, they were clever with what they did. They added a bit of variety to their game, which we haven't seen before. I want people like George North to step up for Wales, I want Leigh Halfpenny to step up.

It's getting quite emotional at the Mochyn Du as Phil Vickery delivers a moving speech about tomorrow's match between Wales and England.
"Rugby has to mean something," the former England and Wasps prop says, looking intently towards presenter Rick O'Shea.
"What's going to make me beat you? The top two inches," Vickery adds, pointing to his head.
Wales must be glad Vickery has retired. The former Celebrity Masterchef winner seems fired up.

It's about the top three inches. It's just a piece of grass just in a different place. The England game has always been the World Cup final for Wales - you know, as long as we beat the English. But it's special.
Post update
Phil Vickery

I love a scrummage and to talk about it, but I don't want it to dominate the game. I want to see the ball moved to the backs, but believe me it will be won and lost up front and I think the reason Wales have the edge is Leigh Halfpenny kicking those scrum penalties.

On the clash between hookers Dylan Hartley and Richard Hibbard
Those two are going to go hammer and tongs at each other for 80 minutes and produce an abrasive physical challenge there.
When Hibbard plays well then Wales do as well because he typifies all about them, the way they want to play on the front foot play. And likewise if Hartley plays well then England do, especially in the set-piece.

Scotland are much better now than they were under Scott Johnson. Under Vern Cotter they are getting better and better, improving with every game and the players are really warming to Vern Cotter.
They have good backs but that's no good without the ball, but the French are very generous people and perhaps they'll give us a bit of the ball.
The odds are heavily in France's favour. But Scotland are much better prepared now and they know what they are doing.

RYAN JONES
No Welshman has won more Grand Slams than Ryan Jones, he was in the sides that completed Six Nations clean sweeps in 2005, 2008 and 2012. He also holds the record for captaining Wales - having worn the armband on 33 occasions - a record that is likely to be beaten by Sam Warburton in this season's tournament.
PHIL VICKERY
World Cup winner and proud Cornishman Vickery played 73 times for England and made five Test match appearances for the British and Irish Lions. A mean prop he is also a whizz in the kitchen, having won the 2011 series of Celebrity Masterchef, beating news presenter Kirsty Wark and actor Nick Pickard in the final.
MATT DAWSON
Another member of the team which won the 2003 World Cup in Australia, Dawson made 77 England appearances and played in seven Lions Test matches. Another Celebrity Masterchef winner (England would hammer Wales in a cooking contest) Dawson has probably won more editions of Question of Sport than he did rugby internationals - quite a feat when you consider he was part of a very successful England side.
Good evening
Hello and good evening from the Mochyn Du in Cardiff on the eve of the 2015 Six Nations.
For our non Welsh-speaking friends, Mochyn Du means Black Pig - but it is not named after the pirate ship in the 1970s children TV series Captain Pugwash.
Will England mount a successful raid against Wales at the Millennium Stadium on Friday?
Matt Dawson, Phil Vickery and Ryan Jones will guide us through the prospects for that game, and the rest of the tournament.

Meet the panel
RYAN JONES
No Welshman has won more Grand Slams than Ryan Jones, he was in the sides that completed Six Nations clean sweeps in 2005, 2008 and 2012. He also holds the record for captaining Wales - having worn the armband on 33 occasions - a record that is likely to be beaten by Sam Warburton in this season's tournament.
PHIL VICKERY
World Cup winner and proud Cornishman Vickery played 73 times for England and made five Test match appearances for the British and Irish Lions. A mean prop he is also a whizz in the kitchen, having won the 2011 series of Celebrity Masterchef, beating news presenter Kirsty Wark and actor Nick Pickard in the final.
MATT DAWSON
Another member of the team which won the 2003 World Cup in Australia, Dawson made 77 England appearances and played in seven Lions Test matches. Another Celebrity Masterchef winner (England would hammer Wales in a cooking contest) Dawson has probably won more editions of Question of Sport than he did rugby internationals - quite a feat when you consider he was part of a very successful England side.
Good evening
Hello and good evening from the Mochyn Du in Cardiff on the eve of the 2015 Six Nations.
For our non Welsh-speaking friends, Mochyn Du means Black Pig - but it is not named after the pirate ship in the 1970s children TV series Captain Pugwash.
Will England mount a successful raid against Wales at the Millennium Stadium on Friday?
Matt Dawson, Phil Vickery and Ryan Jones will guide us through the prospects for that game, and the rest of the tournament.
