So Ireland have made it four consecutive wins since losing the first test of their series triumph in Australia this summer.
Next week sees them host world champions New Zealand, who travel to Dublin off the back of a narrow victory over England at Twickenham today.
Be sure to join us again for live coverage of next week's hugely anticipated Test match - but in the meantime, you can read the full report from today's 28-17 win here.
Peter: Well done Irish-South African-Samoan-etc combination on your win over Argentina!
'We struggled to get rhythm'
FT: Ireland 28-17 Argentina
Speaking to Channel 4, Ireland's Peter O'Mahony said: "They never make it easy for us. They're a world-class side and they're always physical across the board.
"It was a great second half, we struggled to get rhythm in the first half but we earned ourselves penalties and a couple of tries from good, sustained pressure.
"We're going to have to improve across the board. We want to get better each week. We've got two good wins and a nice bit of momentum going into next week."

I think they deserved that victory. It's probably what they expected, a fairly tough Test.
Ireland stuck at it, there's a few guys who have had their first outing since June so it was a bit rusty at times but we'll see a vastly improved performance next weekend against the All Blacks.

That was not quite the
performance that Joe Schmidt was looking for from his side. The Irish players
lacked fluency and made far too many handling errors - particularly under the
high ball, which is normally an area of strength.
It probably shouldn't
come as such a surprise given that so many of these players stayed behind in
Dublin last week when the rest of the squad were in Chicago.
It will, at least,
dampen expectations ahead of next Saturday's match against New Zealand - right?!

Argentina knock on in the final minute and Ireland will probably put this ball straight into the stands once it comes out of the scrum.
Replacement

Johnny Sexton's night is done and he is replaced by Joey Carbery.

No real debate over that
last Sexton penalty. Ireland, with an eight point lead, would normally have
opted for a lineout there but you get the sense that the players want to wrap
this up and get back into the warm dressing-room.
That's Sexton's night
over too...up next the All Blacks.
Penalty - Ireland 28-17 Argentina
Johnny Sexton
Johnny Sexton extends the lead to 11 points after Argentina concede their 10th penalty, just inside their own half.

Ireland 25-17 Argentina
Ireland bring the flare to the Aviva.
After a series of offloads and short passes, the hosts look to make themselves some room on the near side, but Argentina regroup and keep them at bay.
This has been a dogged defensive display by Los Pumas so far.

Ireland 25-17 Argentina
Ireland nearly breach the Argentinian line once more, but the visitors manage to turnover possession and kick clear.

Ireland 25-17 Argentina
Bundee Aki is receiving some treatment for what looks like a twisted ankle. He seems to have shaken it off as Johnny Sexton opts to kick for touch from a penalty.
'Very soft try'

Darren Cave

Argentina will be very disappointed. They defended about 30 phases of play then they conceded a very soft try.
'Breaking point'

Andrew Trimble

Ireland have been banging on the door and Argentina have been hanging tough for so long but everyone's got their breaking point. Argentina's breaking point came later than we expected.
Conversion - Ireland 25-17 Argentina
Johnny Sexton
The Leinster fly-half adds the extras from in front of the posts.
Try - Ireland 23-17 Argentina
Luke McGrath
CJ Stander picks up the ball at the back of the scrum, before feeding the replacement scrum half, who uses speed and guile to bypass the defence and score under the sticks.

No try - Ireland 18-17 Argentina
Dan Leavy
Ireland punch through under the posts, but substitute Dan Leavy is adjudged to be held up. It's a 5-metre scrum to come.
Post update
Ireland 18-17 Argentina
Argentina are stepping up in defence with real speed but the Ireland battering ram rumbles on into the 19th phase. Surely this level of defence cannot be sustained.
