Former Wales fly-half on BBC Radio 5 live sports extra"They've both come to play. There have been so many half breaks. Argentina were too fast and loose in the first 10 minutes. They've tried to adapt and they have to learn when to use their strengths."

Argentina are throwing it about with abandon. As they must. Joaquin Tuculet darting up into the Aussie 22m, but the support is sluggish.
There are some tired Argentines out there.

The replay of the scoring pass between Drew Mitchell and Adam Ashley-Cooper suggests the ball drifted forward between the two Australians.
It looked fine on first viewing, but Wayne Barnes would have had a tough call to make had he sent it up to the big screen.

This has gone for the Pumas.

Image source, ReutersA Bledisloe World Cup final it is then.
Drew Mitchell cuts the Argentina defence to ribbons with an electric burst and then jagging step off his left wing. Blue and white shirts falling off the Wallaby and he finally manages to connect up with fellow wing Adam Ashley-Cooper for a stroll in.
That is Ashley-Cooper's hat-trick. And Bernard Foley rubs salt into the wounds.

Another over-ambitious off-load from Argentina and Australia snatch the ball back.
Are the Pumas trying too hard? A little more brain and a little less adrenaline and they will be able to find a way through Australia's defence.

Australia are continuing to dominate the turnover count as they have done throughout the tournament, winning nine to Argentina's four. And that man David Pocock is leading the way...

Butterfingers. The ball gets away from Kurtley Beale on halfway and the Pumas snaffle possession.
There is space for whichever team has the ball in hand...

Pocock's work goes to waste though as Michael Hooper is boshed by Marcelo Bosch in midfield and the Pumas fly-hack upfield.

Australia full-back Israel Folau was a doubt for this game and it looks like his race is run.
Matt Toomua is on in his place.

Australia come up with the turnover just when they need it.
And they were gifted it by scrum-half Tomas Cubelli whose toe stubs the ball into the path of Tatafu Polota-Nau.
A basic mistake to allow the Aussies off the hook when the Pumas had them pinned in the 22m.
