Ireland's confidence is sky high as they welcome Argentina to Dublin just a week on from their famous victory over the All Blacks.
Andy Farrell's side were deserved victors last time out as they were simply the better side in what was an enthralling match at the Aviva Stadium.
Now, though, attentions must turn to the visit of Los Pumas, who can cause plenty of problems of their own.

What is the Ireland v Argentina team news?
Robbie Henshaw returns to the Ireland side for the first time this season as Andy Farrell makes four changes to the side that beat New Zealand.
The two-time Lion replaces Bundee Aki, who has a minor knee issue, at inside centre.
Inside Henshaw, Conor Murray and Joey Carbery form a new half-back partnership after Jamison Gibson-Park and Johnny Sexton were both ruled out with injuries.
Out wide, Ulster's Robert Baloucoune comes in to start in place of Andrew Conway. The pack remains unchanged.
Argentina, who have never won a game in Dublin, have made three changes to their starting line-up following a win over Italy last weekend.
Guido Petti has recovered from knee trouble to return to the second row, while Santiago Grondona comes back in on the blindside flank, with Pablo Matera moving to No.8.
Out wide, Lucio Cinti comes in for Santiago Cordero on the wing.
