Argentina hung tough there for a long period. It looks like Ireland have said to themselves, 'we've tried taking them on up front so why don't we just do what we do best.'

It's a real shame to see Kieran Marmion go off, it was a real opportunity for him to step into Conor Murray's shoes.

Johnny Sexton keeps his head down as he strikes through the ball from just inside the Argentinian 10 metre line, and the flags go up.

Ireland go through the motions again and play swings from right to left. In the end, Argentina give a penalty away in a central position for a lack of discipline at the break down. Johnny Sexton has grabbed hold of the ball...

Ireland are starting to turn the screw here. The ball's being delivered at a high tempo, Will Addison's in the middle of everything and Ireland are really getting into their stride.

Emiliano Boffelli makes a good break but his chip ahead is collected by Johnny Sexton, who keeps hold of the ball, before Kieran Marmion clears with the boot.

Ireland, buoyed by the crowd, run the ball off the back of a rolling maul. But Argentina's defence stand firm and they win the line out after the hosts fumble the ball into touch.

Ireland are getting a bit of momentum and their phase play is starting to look sharp.

With the penalty just inside the Argentine half, the Irish 10 gives it a good old nudge, but his effort just falls short.

Ireland respond and go through the phases with some neat passing in tight areas. Johnny Sexton kicks the ball away knowing play would come back for a high tackle against him. It looks like it will be a shot at goal.

That's a bit of a wake-up call for Ireland. If this Argentina side get a foothold up front, they're a serious threat behind the scrum.

The Argentine fly-half makes it four penalties from four and the lead swings again.

Argentina enjoy a period of sustained possession at the start of the second half and Ireland are penalised for tackling on the ground. Nicolas Sanchez is poised to take the resulting penalty.

We are back under way at the Aviva.

Both sets of players have returned to the pitch. We're all set for the second half.

We expected Argentina to come out and be aggressive in defence and they have been. They're capable of scoring tries if you give them the opportunity.

They've relied a lot on high kicks, Jordan Larmour maybe isn't as comfortable under them as someone like Rob Kearney. Ireland have let themselves down with small errors and it's cost them dearly.

The crowd at the Aviva Stadium are a little on edge after that half. Ireland have the edge in the set-piece but Schmidt will be furious with the indiscipline shown by his players which has allowed Sanchez to keep Argentina in touch.

The Pumas fly-half won't be too happy either. He thought referee Nic Berry was playing an advantage at the end of the half, which is why he attempted the drop goal. Overall the visitors have been more clinical with their chances.

It's evenly balanced here and that's making the crowd a little nervous.

Simon Gleave, head of sports analysis, Gracenote: The 14 first-half points conceded by Ireland are the joint most they have allowed in the first 40 minutes in their last 20 Tests. Australia also scored 14 first-half points in Ireland's 26-21 win in the second Test of this year's summer tour.

This Argentina side is used to grinding it out. They're used to getting a hard time, they play the All Blacks regularly. They've had a couple of purple patches but it's been a sloppy first half.

Nicolas Sanchez watches his attempted drop kick drift wide of the posts as the referee brings the half to an end.
