Argentina against the Netherlands on Friday should be a good game.

Unless you are Australian, you can't help but enjoy this whole occasion.

The stadium is almost as one - barring the small pocket of yellow-shirted fans - as the fans put their arms together and bounce from side to side.

You get the feeling they really believe this could be their year... and with support like this, surely they have a big chance.

Julian Alvarez closes down Mat Ryan as he deals with a backpass and the Australia keeper has learned his lesson as he kicks the ball away.

Straight after that goal Australia brought on Craig Goodwin and Ajdin Hrustic for Riley McGree and Keanu Baccus.

Julian Alvarez is the sixth player to score in each of his first two World Cup starts for Argentina, and the first since Hernan Crespo in 2006.

That's been coming a little bit. Mathew Ryan is a good goalkeeper in many ways but he is not good with his feet. He didn't look that comfortable to me.

You cannot do that. That was massively poor to be caught out like that. Ryan has killed it for Australia. It's a bit daft. If you haven't got the skills, just launch it and he hasn't got the skills.

It's a better press from Argentina, really good. But I don't know what the keeper is doing.

It just shows you, if you do press, take a gamble, and go together you get your rewards.

That could be the goal that seals their quarter-final place.

James: That was Messi’s first ever goal in the knockout stages of the World Cup. He has some way to go to match Pele, Maradona and Brazilian Ronaldo in this regard.

Good spell of possession from Argentina. Mat Ryan has to run out of his box to head the ball out of play.

Here is Lionel Messi's first World Cup knockout goal.

Really good from Duke again, trying hard to close people down and get up the pitch.

Twice now Mitchell Duke has closed down and blocked Emiliano Martinez. This time Martinez just gets there first to Nicolas Otamendi's backpass.

As a fan you love to see a striker chasing the ball down like that.

Argentina have gone to a back five now. Interesting to make a change like that so early in the second half. What has Lionel Scaloni seen?

Just slipped as he hit it. Lost his footing.

Lionel Messi slips as he shoots from near the penalty spot and it's a simple one for Mat Ryan. Messi remains the only player to have a shot on target here.

This is very unusual.

Argentina bring on Lisandro Martinez, a centre-back, for Papu Gomez, a forward. Why not at half-time? Why at all?

Here is the Lionel Messi goal which separates the teams so far.

We know that Mathew Leckie is good on the ball and quick as a wide player.

Yikes, Argentina keeper Emiliano Martinez takes his time to clear the ball and he's closed down by Mitchell Duke. Luckily for the South Americans, the ball bounces to safety.
