Andy Farrell believes Ireland will have no problem matching Wales' passion when the sides meet this Saturday.

The vast majority of the Grand Slam champions' players ply their trade with Welsh clubs and rarely get to experience knock-out rugby on the European stage.

That has led to the theory that, as opposed to the Irish set-up where the provinces are regularly involved in high-stakes rugby after the Guinness Six Nations, they can channel more emotion into the national team efforts.

While the new head coach, whose side got off to a nervy start with a win over Scotland last Saturday, reckons they won't be found wanting, he did admit that the topic had come up in conversation.

"Every Test match, you've got to get the emotion right, some weeks more than others," Farrell told RTE Sport after making two changes to the team for the clash at the Aviva (2.15pm). 

"What you've touched on there is something that the lads have spoken about themselves, today funnily enough.

"They're good players. They're good professional players. They know how to get themselves right for the weekend and we'll help them do that."

Prop forward Cian Healy, who has won four Heineken Champions Cups with Leinster, was also asked about the subject and whether it's possible to work on matching the famous Welsh passion.

"I'm not sure it's [about] matching them," said the 32-year-old.

"We've got a lot of national pride and we've got a lot of club pride. This came up years ago in one of the infamous meetings about 'play for your country as you play for your club'.

"That's not really an issue here. Lads come in and it becomes one team, you are expecting higher standards across the board.

"We enjoy doing what we do and we enjoy being together. That, without any effort, creates a drive to succeed together and to enjoy those times.

"I wouldn't be too much into looking at how other teams get up for games.

"You might look at what drives them but we are kind of set on what their tactics are and how they want to try and stretch our defence and such but it's kind of all about us from this side of it."
