Joe Schmidt is a big fan of Will Addison's and you can certainly see why. The Ireland coach played an instrumental role in enticing Addison over to Ulster from Sale Sharks and he has looked like a prototype Schmidt player in his first Test start.

He's been heavily involved in all of Ireland's best attacks so far and he's communicating well with Sexton and Aki in that midfield defence.

The beauty of his inclusion for Henshaw is that he's almost a like-for-like replacement both physically and in terms of skill and Ireland have used his size to attack their restarts

The Irish talisman puts his side in front once more with a well-struck penalty after Sean O'Brien departs the field.

Slight pause in play now as Sean O'Brien receives some treatment from the physios for what looks like a wrist issue.

That's a bit of a shame for James Ryan, he did everything right. I think he got done for taking out the nine but that's really unfortunate. It's an illustration of the day so far, Ireland have done everything right but then they're just giving away penalties.

That's three from three and that's the best of the lot from left of the posts. Argentina retake the lead.

Bundee Aki is penalised for a late tackle on Nicolas Sanchez, and the Argentine fly-half will dust himself off before having another crack at the posts.

Ireland lose another line out after a knock on by James Ryan. It should have been an attacking platform for Ireland but it gives Argentina another chance to attack.

With half an hour on the clock, Ireland are playing the better rugby, but they need to reduce their penalty count.

John McEnerney: Argentina always start well against us, remember World Cup 2015. Sexton will start barking orders all over the shop now & get the troops in line. Ireland will unleash on the Pumas now!

Ireland are fortunate to turn defence into attack as Argentina's Garryowen kick lands favourably deep inside the Irish half, and Jacob Stockdale is able to clear his lines.

It's a power game from Ireland, that's a bit of a Joe Schmidt signature. Once you get in the 22, you come away with the points.

The Irish fly-half adds the extras from a relatively easy range. Ireland regain the lead.

What a sensational break by Matias Orlando that led to that Delguy try! Ireland's scramble defence was poor and I have every sympathy for poor Rory Best, who was left one-on-one against one of the most dangerous wingers in world rugby - only one winner there!

Ireland have a line-out deep in the Argentine half, but the ball is knocked forward in the forwards as they relieve pressure on their opponents once more.

Argentina started narrow and predictable but that last passage of play was different - it was dynamic. It was a lovely pass from Sanchez in the end to make the extra number count.

It's a let-off for Ireland as Nicolas Sanchez misses the conversion. The visitors lead by six points.

Ireland look comfortable defensively but they just ease the pressure on Argentina once again by conceding a penalty for a high tackle. It allows them to enter Ireland's half.

Argentina hit back and win a penalty in the Irish half. The visitors regain the lead as Sanchez keeps his cool to make it two kicks from two attempts.
