Yes Nicky, that settled Biggar - Tompkins - North axis is really purring.

Wales' backs have been brilliant so far, so slick.

Every time they've had the ball they've created problems for the Argentinian defence.

Referee Jaco Peyper is holding his hamstring and is now going off.

I think he tweaked it trying to keep up with that Welsh attack!

It was that late decision from Dan Biggar, he obviously heard George North screaming at him for the ball.

They attacked Santiago Carreras and Wales made it look easy, but there was a lot to do!

Brilliant by Wales!

They're [Wales] going through the width quite a lot through set-pieces, they're forcing the Argentinian defence backwards.

Brilliant to see moves off the scrum working so well, Dan Biggar and Gareth Davies combining with the loop which creates the extra player on the outside.

But after that George North splitting the Argentinian defence down the middle and Davies there in support and Biggar there under the posts.

Well, he said he did not want this to be his last game in a Wales jersey and he's doing his best to make sure it's not.

That's only his eighth test try.

More numbers are falling off the Welsh jerseys. This is bizarre.

Surely they will have to do something about this at half-time because the referee cannot idenitiy the players.

I'm not sure Wales' forwards are happy with Liam Williams taking that dropout quickly.

Liam Williams takes a quick drop out, gathers but it swamped by white and blue jerseys.

Wales do have one issue however, all their numbers are falling off.

Liam Williams, Rees-Zammit, Will Rowlands and Josh Adams barely have numbers left on their jersey.

Did they use selotape?

To be fair Josh, I think they are...

Just get him the ball [to Louis Rees-Zammit] as quickly as possible!

Warren Gatland said he wanted to see Louis Rees-Zammit with his hands on the ball far more and he's just got it again.

He could be right in the thick of it today.

I noticed a couple of phases earlier that we're living right on the edge of their back foot and we just need to give that slight half a yard, so we're not giving silly penalties away.

Dan Biggar loops around in midfield to create space for Louis Rees-Zammit but his kick ahead is just too far and Boffelli covers.

You have to say well done Aaron Wainwright, great turnover.

It all came from Santiago Carreras threatening to kick and then throwing the ball wide but Wales did well to scramble back in defence.

Emiliano Boffelli pushes it across the posts and we're still level.

He missed a couple last week against Japan as well.

Well it's certainly got the Argentina fans going, they are making one hell of a racket.

It's a penalty to Argentina, but Wales will be grateful it's not more.
