15 Jordan Larmour (6/10)

Coughed up an early penalty that was brilliantly nailed by Nicolas Sanchez and was lucky that the visitors didn't pounce when he badly misjudged a garryowen under his own posts, when only a kind bounce got him off the hook. Looked uncomfortable in the air all game. Rob Kearney would have been nervous watching Larmour in Chicago last week; today underlined the value of the elder statesman's experience. 

14 Keith Earls (7.5/10)

Caught cold under a first-half high ball that led to Argentina's second penalty and then knocked on after a Pumas' restart. Improved in the second half, making good yards when the chance presented itself.

13 Will Addison (8/10)

Dropped in at the last minute in place of the injured Robbie Henshaw but seemed to settle immediately, getting his hands on early ball to ease any nerves.  After that he was really assured; solid carrying, sound defensively. Did his prospects no harm. 

12 Bundee Aki (8.5/10)

Great awareness to skate through for his try having been hit with a bone-shaking tackle just moments beforehand. A guiding light for Addison after Henshaw's late withdrawal, the sight of him on the turf wincing with pain after going over awkwardly on his left ankle had Irish hearts in mouths. Thankfully seemed to shrug it off quickly enough. 

11 Jacob Stockdale (7/10)

He started well, faded but grew in stature on the turnaround as he looked to pick holes in the Pumas defence. A sporadic menace but rarely found the kind of space he requires to do serious damage.  

10 Jonathan Sexton (6.5/10)

A pulled conversion, a couple of misjudged crossfield kicks, a penalty that dropped short and some eyebrow-raising decision making - this was a frustrating day at the office. 

9 Kieran Marmion (8/10)

Took his fourth Ireland try with devastating efficiency and also made one excellent tackle on Ramiro Moyano. Hobbled off with a rolled ankle but Joe Schmidt said afterwards that he expects him to be okay for next week. Had done well in his 57 minutes. 

1 Cian Healy (8/10)

Helped create the first two tries as part of a marauding scrum that just bullied Argentina into submission. The front-row showing was the bright spark from an uncharacteristically error-ridden first 40 from the hosts.

2 Rory Best (6.5/10)

He'll be massively frustrated with the lineout. Nothing seemed to click, from the delivery to the calls to the execution. The introduction of Devin Toner on the hour seemed to finally relax things. A tough return to the captain but he did get through some great front-row work which laid the crucial scrum platform.

3 Tadhg Furlong (8/10)

Good work around the breakdown, immense in the scrum (on the few occasions he got to flex his muscles in that area) and punched holes when he got the chance.

4 Iain Henderson (6/10)

Had a really patchy first half with the lineout and was part of a general struggle to cope with the Pumas' quick, accurate restarts. Could well have played his way out of the team. 

5 James Ryan (9/10)

Will have to face up to the inevitable setpiece inquest but once again the 22-year-old's phenomenal appetite for hard work compensated for a few moments of poor concentration in the first half. Seventeen carries, 12 tackles, and right at the heart of a monster Irish scrum all night. 

6 Peter O’Mahony (8/10) 

Ripped away some good ball and was typically unforgiving at the breakdown. One great steal off a lineout lifted the natives.  

7 Sean O’Brien (7/10)

A huge shame to see him leave the pitch cradling his arm after making his first start for Ireland in nearly a year. It was an innocuous looking tackle on Tomas Lavanini too, in which O'Brien's forearm appeared to catch the lock's head. Understandably distraught and facing a long spell on sidelines.

8 CJ Stander (8/10)

Showed unbelievable leg power to drive over in the seventh minute, just about being held up by the Argentinians, but controlled the scrum two minutes later to give Marmion the opening he capitalised on so clinically. Turned over some good ball.


16 Sean Cronin (for Best 60 mins) (7/10)

Straight into the thick of things in a strong Irish finish, good tackle count and good carrying. Helped in the lineout.

17 Jack McGrath (for Healy 53 mins) (6.5/10)

Maintained the good work his team-mate had established in the scrum. 

19 Devin Toner (for Iain Henderson 60 mins) (7/10)

His stock soared in the hour he was sitting on the bench, and then provided a safe pair of hands in what had been an alarmingly inconsistent lineout. 

20 Dan Leavy (for O'Brien 38 mins) 8.5/10

Was unlucky to concede the early second-half penalty that allowed Sanchez to nudge Argentina ahead - it looked like he couldn't avoid the trailing leg he was penalised for - but he didn't dwell on that. Was at the heart of so many positives for Ireland when they really needed it; looks like he's earned a start against the All Blacks. 

 21 Luke McGrath (for Marmion 57 mins) 7.5/10

Great feet for his try 15 minutes from time as he followed Marmion's lead and made hay off Ireland's massively effective scrum.

22 Joey Carbery (for Sexton 76 mins)

Not on long enough to rate.

23 Andrew Conway (for Larmour 76 mins)

Not on long enough to rate.
