Away we go.

Both teams are in their traditional colours - Argentina in sky blue and white; Scotland in navy blue.

Only me that cares about that sort of thing?

Flower of Scotland rings around Murrayfield and smoke from fireworks dissipates into the clear autumn sky.

It's a wee bit chilly in the capital, but there's not a breath of wind. Perfect conditions.

The players emerge from the tunnel - Darcy Graham leads Scotland out on his 50th cap.

He's got a massive grin on his face.

Juan Martin Gonzalez and Juan Cruz Mallia are making their 50th appearances for Argentina also.

Supporters are still streaming into Murrayfield 10 minutes before kick-off.

The atmosphere was superb against New Zealand last week and it's another packed house today.

Scotland head coach Gregor Townsend tells BBC Radio Scotland: "Late last night I got a message [about Ben White] just before I went to bed. It was just bad timing. He's still feeling ropey this morning.

"Both nines played well last week. It's a great opportunity for [Jamie Dobie]. We definitely want to see his strengths, which are his running game and also his defence.

"[Argentina] are a tough opposition. They're a very cohesive team. We know each other well - coaching groups, we know each other well, we were playing five-a-side football the other night.

"I've been really impressed with Argentina, I've got a lot of respect for the rugby they play and the improvements they've made.

"Similar philosophies. We want to move the ball around and play at pace and we back our players to make decisions. I see that with Argentina but they do defend differently. They go to the air a bit more because they've got some excellent players in the air.

"We have to win because that's our job here."

What do you reckon?

Is Townsend the man to take Scotland forwards? Hit those thumbs.

To be competitive in the World Cup, you have to beat the likes of New Zealand or South Africa.

Is Gregor [Townsend] the guy? I don't think he is. I think he's run his course.

We have a guy in the background who could take us to that next stage, Franco Smith.

Over the years, you have always worried about Argentina's physicality - they are horrible to play against and full of aggression.

But they now also have a back division that are world class.

You only need to look at Argentina's last outing for a sense of what Scotland are up against today.

Los Pumas powered to a record win over Wales in Cardiff last weekend, scoring seven tries in the 52-28 victory.

A quick scan of the 23-man squad tells you Argentina are a serious team. Eighteen of them play in the top division in England or France.

Inside centre Santiago Chocobares has been a vital cog in the Toulouse winning machine, scoring in last season's Top 14 final, and has a serious argument to be considered the best in the world in his position.

Santiago Carreras, the leading points scorer in this year's Rugby Championship, is one of the best in the world off the tee, never mind the electric ability in open field he has shown with Gloucester, and now Bath, in the past five years.

Carreras is not even in the starting team for Murrayfield.

Among the forwards, the Pumas' most-capped player ever, the bruising and gnarled Pablo Matera, is also on the bench, while captain Julian Montoya, a Premiership winner with Leicester Tigers, leads from hooker for his 116th cap.

Argentina have always had world class players. Head coach Contepomi was in the team that stunned the sport by finishing third at the 2007 World Cup.

The difference now is the depth of squad and the depth of experience of playing top-level rugby across the world.

We are now at the stage where we are creating all these chances when, for years, we were relying on the boot of a Chris Paterson or Dan Parks, or Greg Laidlaw.

We just have to start taking them as we can't allow a team like New Zealand or Argentina to establish a lead.

Darcy Graham brings up 50 caps for his country today.

The 28-year-old has 34 Test tries, the current record alongside team-mate Duhan van der Merwe.

Reflecting on his journey from playing with his hometown team Hawick to a half century of caps, Graham said he would never have expected to reach this landmark.

"I've got half of Hawick coming up so it should be an awesome atmosphere and special day," he said.

"They come up in numbers so it will be class having them there to share a special day.

"Playing for Hawick feels like yesterday and I'd love go back and play for them and play with my pals again.

"Fifty caps has come up quickly and I've had my injuries along the way. That's part of the game and it's the way I play, I put my body on the line"

Scotland winger Darcy Graham came agonisingly close to his 35th international try against the All Blacks.

Kiwi scrum-half Cam Roigard knocked the ball from Graham's grasp with the try-line - and the lead - beckoning.

He was devastated after the game last week, but reaches a special landmark this afternoon...

A lovely dose of optimism, Peter.
