"Fantastic play from Argentina working their play from side to side and making progress up the field. Conrad Smith will argue that the ball was out and he was going for the ball. But the All Blacks are really scrambling."

Will the Pumas opt for the posts? Yes they will and Nicolas Sanchez cannot miss from there. Another three points and they open up a four-point lead. 

New Zealand reduced to 13 men. Juan Imhoff breaking loose once more but he's stopped agonisingly close to the posts.. Conrad Smith supporting the tackler but is off his feet at the ruck. 

Argentina unwilling to be cowed by reputation. The Pumas confidently spinning the ball and running from their own half. Juan Imhoff raises the crowd's voice with a dash down the wing... Argentina rumbling on...

The All Blacks puncturing holes in the Argentine defence,.. New Zealand threatening... Conrad Smith and Ma'a Nonu looking menacing... the men in black ease to withing 5m from the Argentine line but the Argentine defence is as tough as teak. Kieran Read loses the ball in the tackle and the Pumas can breathe again. 

As an open-side flanker, the ex-England and Gloucester man may know a few things about the dark arts of rugby...

Argentina oozing confidence and they attempt to take it to the All Blacks from their own half... they've got the overlap but Nicolas Sanchez spills the ball and that is that.

"Argentina have got past their jitters and they're giving it everything. They've got the crowd right behind them too."

"Richie McCaw has had run-ins with Wayne Barnes in the past. I think McCaw was trying to do one of those cynical things that flankers do. I'm not making excuses for him, but he's not the only flanker who does that sort of thing."

Nicolas Sanchez charged with sticking the knife in and that's what the orange-booted outside-half does. A super effort from just inside the All Black half. There couldn't be another World Cup upset, could there? 

The crowd hiss as Richie McCaw receives a yellow card for tripping Juan Martin Fernandez Lobbe as the back-rower attempted to take a quick free-kick. The All Blacks down to 14 men and they could soon be behind, too.

Ma'a Nonu bounces off one would-be tackler... Kieran Read, as ever, in support... The All Blacks working it along the backline... Nehe Milner-Skudder scoops up Dan Carter's pass and attempts the offload but Sam Whitelock fumbles 10m from the line. The All Blacks huffing, the All Blacks puffing...

With Pablo Matera in the bin and Argentina down to 14 men, you would expect the Pumas to be on the back foot.

But New Zealand are having to do most of the defensive work with the Pumas a man down, with 34 tackles to Argentina's 22, and the All Blacks have missed a further eight.

The Pumas have also made more metres and carries during this spell.

The man leading  New Zealand's defensive efforts? Who else but captain Richie McCaw with seven tackles.

Guido Petti has had to leave the filed with a head injury but he's made his mark on the match. His team currently having to defend without him.

"One of the things Argentina weren't good at when they lost to New Zealand in Christchurch in the Rugby Championship earlier this year was manipulating space and putting each other into gaps. Already, we've seen an improvement in that."

What a difference 10 minutes make, Argentina have grown into this game and have begun dominating possession, although New Zealand have still enjoyed the better of territory.
