The back row need to carry, carry and carry again. They all need to be in the double figures, it will be interesting to see how Ritchie does with the turnovers.

Townsend has said this is the in-form back row which I think is harsh considering Andy Christie has been tearing it up in the Premiership.

Cam Winnett gets his first touch at international rugby.

Looked confident and takes the ball up.

Lineout Scotland.

So the anthems are done... two crackers.

There's a thin cloud of smoke hanging above the pitch, trapped under the closed roof.

The people in the top rows may be looking through pea-soup for a few minutes.

Sam Costelow gets us underway.

Game on!

I'm sure Scotland fans are tired of hearing about this, but...

I think Kyle Steyn is one of the most underrated players in international rugby.

He is scoring a try almost every game and a half. That's a faster rate of try scoring than Duhan van der Merwe.

I'm the same as Ian Gough, my heart will always say Wales but the reality from my head says Scotland.

I'm going Scotland by 8-10 points.

And now Mae Hen Wlad Fy Nhadau

I think it's massively against Wales, with the bookies' favourites Scotland coming down.

At the minute it's looking like a Scotland win.

To get a good start to the Six Nations, to put a guy like Kyle Rowe at full-back, it is a big call. He's never played there before, certainly not at Glasgow. I would be more comfortable with Huw Jones there and Redpath in the midfield with Tuipulotu.

The back row combination I'm not particularly comfortable with, Crosbie and Ritchie have been playing well but Ritchie gets too involved and rubs the referees the wrong way which is possibly why he lost the captaincy.

The front five need to work well. Gray and Cummings need to get the line outs working well for them to have a chance.

The Welsh Rugby Union will now be delivering a period of applause in recognition of former Wales internationals Brian Price (Newport), Malcolm Price (Pontypool), Bill Morris (Newport), Bryan Richards (Swansea/ London Welsh) and JPR Williams (London Welsh/ Bridgend).

JPR got a huge ovation then from this Cardiff crowd. Respect.

Wales historically build their game on a stubborn defence. If that side goes well and they make Scotland work the Scots are going to become frustrated and then make errors.

If Wales can throw Finn Russell off his game then anything can happen. Nobody expects Wales to win so the pressure is all on Scotland.

Did you watch The Traitors? Great, wasn't it? What do you mean, no? That's not very faithful...

Anyway, one of the finalists, Andrew Jenkins, has been spotted at the Principality Stadium.

He's a big man. Wales could probably do with that muscular frame today. Wonder if he's brought his boots?

At the moment, on form, Finn Russell is one of the best 10s in the world, while Sam Costelow is at the start of his international career.

Russell has blown hot and cold this year, consistency at stand-off is what you look for. If he has his mojo then he will cause Wales no end of trouble.

Is Finn Russell the Lionel Messi of rugby?

Scotland's co-captain has been talking about his "jokey comment" comparing himself to the football icon in Netflix's new Six Nations documentary.

More roof chat? If you must.

Wales lock Adam Beard says the atmosphere created under a closed Principality Stadium roof will give the home side a huge boost against Scotland in the Six Nations.

The Scots had initially asked for the retractable roof to be left open for the game in Cardiff, but made a U-turn on Friday, requesting it be closed with rain forecast.

Scotland head coach Gregor Townsend has been chatting to BBC One, and started by talking through the roof u-turn:

"The weather changed. Nobody wants to play in rain if they can avoid it. We'd have preferred a dry day, but we're all happy now.

"We believe this team has experience of winning in venues we've not had great records in, so this is another one to challenge us today.

"The squad selection doesn't win games. It's what you do in the 80 minutes that count.

"Finn won't change how he plays [as captain]. He leads our attack anyway, he's a good connector with his team-mates and referees."

What a day for Dafydd Jenkins.

Following injuries to Jac Morgan and Dewi Lake, Jenkins will be 21 years and 60 days when he becomes Wales' second-youngest captain in history.

Only a certain Sir Gareth Edwards was younger, aged 20, when he led Wales for the first time, also against Scotland in Cardiff, during the 1968 Five Nations.

And how about this... Jenkins was not even born the last time Scotland beat Wales in Cardiff.

He has rugby pedigree. His father, Hywel, played for Wales in a non-capped match against America. He was known as "Crazy Horse" with his friends calling his son "Baby Horse".

You can read about his journey from Porthcawl to the Wales captaincy when he leads out his team in less than an hour.

Scotland may have lost Blair Kinghorn and Darcy Graham - but they still have Duhan van der Merwe.

"One of the best one-on-one attackers in world rugby" was how Gregor Townsend described him on Thursday.

In an explosive international career, Van der Merwe has scored at a near-historic lick, 21 tries in 34 games.

That strike rate is closing in on Ian Smith's numbers from the 1920s, when a win was worth two points, a try worth three and the championship consisted of four teams.

This time last year some people were calling him Van der Swerver after he ran inside, outside and through all those England defenders at Twickenham.

Yet bizarrely, the only Six Nations side he is yet to score against is Wales. Four games, no joy.

Could that change today?

Wales head coach Warren Gatland believes Cameron Winnett can thrive on the international stage after handing the Cardiff full-back his debut against Scotland in the Six Nations on Saturday.

Winnett, 21, who will line up for only his 16th professional game, has impressed this season for his club and has been given a vote of confidence from Gatland.

Scotland's squad today throws up a pretty remarkable statistic.

With Darcy Graham injured and Glen Young not picked, it's the first time in 99 years that no Borderer has been selected for Scotland.

It was Scotland's last ever game at Inverleith in February 1925 - they beat France 25-4 in the Five Nations on their way to winning the Grand Slam.
