Following on from the success of their 2014 Six Nations triumph, Ireland head to South America for a summer of further improvements under Joe Schmidt.
The former Leinster head coach has already made a significant impact on the Irish setup, but the summer tour of Argentina presents him with a new challenge.
Ireland begin their summer examinations on Saturday against a Pumas line-up that's lacking a lot of its European-based players, but Daniel Hourcade's men are still likely to pose stiff competition for the Irish.

Key Players to Watch
Argentina: Nicolas Sanchez
One of the few high-profile names to have made their way back from Europe in order to feature this weekend and beyond is Nicolas Sanchez.
The Bordeaux fly-half is expected to start in what could be a pivotal one-on-one clash against Jonny Sexton, likely to dictate just how the hosts will stand up on the scoreboard.
In last year's Rugby Championship, the Pumas made it a point of theirs to always begin games at a high tempo, especially when featuring at home, so one might expect Sanchez to take his chances at goal early on in the hope of building a swift lead.
Ireland: Robbie Diack
Schmidt is likely to hand a number of improving youngsters their opportunities to impress in Argentina, and Ulster's Robbie Diack will hope that he can win his first international cap as early as this weekend.
It's only been a week since Leinster defended their Pro12 title, so a lot of their stars are likely to miss out, which could lead to Jordi Murphy and Rhys Ruddock taking a back seat.
Ulster at least have confidence in the potential to come from their forward, after RTE announced that he had put pen to paper on a three-year deal at Ravenhill back in October:
Should the aforementioned Leinster men miss out, 28-year-old Diack will take to the back row with an air of opportunity about him, perhaps looking to replicate the same stellar rise that Chris Henry has experienced over the past year.
Tomas Cubelli vs. Conor Murray
Munster's inconsistent form will have been difficult for many at Thomond Park to take this season, especially the longer-term staples who are used to something a lot more solidified.
Conor Murray hasn't long been the No. 1 choice at scrum-half for the club, but his election as Player of the Year at least showed that he managed to piece together some impressive displays:
Opposite him this Saturday will be Tomas Cubelli, a darting half-back who, while not of the same stature as Murray, also possesses the potential for weaving his way around the fringes and causing a fright among defenders.
Each scrum-half will need their wits about them in what should be an enjoyable contest between two figures who aren't afraid to run the ball, but there lies a bigger duty with Cubelli to ensure that his backs receive good service in a bid to overcome their foes.
