After edging Scotland at the Aviva Stadium last Saturday, Ireland face a stiff challenge as reigning Six Nations Grand Slam champions Wales visit Dublin this week.
But one thing that unites both nations is the fact that they are both under new head coaches.
Wayne Pivac slots into the Welsh leadership role long occupied by Warren Gatland as both he and Andy Farrell aim to make it two wins from two.
But what can the Irish side expect from a Welsh team that began the 2020 campaign with a resounding win versus Italy?
Former Ospreys head coach Sean Holley joined RTÉ 2FM's Game On to share an insight into a team that just missed out on a place in the Rugby World Cup final just over three months ago.
"I think Wales will grow into this tournament. It's been an easy start," he said.
"The core of the team is strong and experienced so I would imagine they go [to Dublin] with a little bit of confidence.
"But that performance, don't forget, at the end of last year's Six Nations in Cardiff for the Grand Slam was very, very dominant from a Wales point of view and that will give them a lot of confidence too."
A different proposition under Pivac, Holley highlighted some of the early signs of change that were visible against Italy last week.
"They're certainly running the ball back a little bit more," he said.
"Whether that will be the case this week, I'm not so sure.
"But even with Leigh Halfpenny in the back field there, he was counter-attacking a lot more whereas we've been used to seeing him and Dan Biggar pump the ball back in the air and have a contest.
"They're both very good at that but there was definitely an intent to run it back.
"There was also a little shift in the alignment of some of the players. We saw Alun Wyn Jones in the wide channels.
"We're used to seeing our hooker out there under Wayne Pivac with the Scarlets. But they swapped them around.
"I think he's looking for a few seat belt tackles in midfield on the shorter men and having the bigger men out wide.
"But the last thing, and one I've got a really keen eye on, is Jonathan Humphreys is now the forwards coach and I think that's an area we can really improve.
"Although our scrum wasn't great last week, I certainly saw a difference in the lineout where [Justin] Tipuric was being used a lot under Warren Gatland to take the ball, whereas he was playing at half-back, he was out in the back field - very much a pivot.
"So there has been a marked change already and I expect to see a bit more of that this week."
