The Scarlets read the script, Munster tore it up.

Johann van Graan made 11 changes, picked a new captain in Jack O'Donoghue, and included a handful of seasonal debutants, the stage was set for a packed home squad, which had three returning Lions in Ken Owens, Gareth Davies and Wyn Jones, to get the job done.

The visitors had four internationals in their starting XV, Scarlets had 11.

"It’s a full deck. It’s a big ask given [Munster’s] inexperience in a lot of areas," said Donal Lenihan, on RTÉ Sport co-commentary duty, before the game.

"The most important thing is our squad," said Van Graan when asked pre-match about taking a risk in switching out so many players.

"Guys have earned the opportunity...I’m really looking forward to seeing these lads playing. It’s about using your opportunity."

And that they did.

Either side of a five-minute purple patch by the hosts, when they notched 10 of their 13-point tally between the 29th and 34th minute, Munster were in control, eventually running out 43-13 winners.

Six tries, one conceded, solid set-piece, winning all seven scrums and all bar one of 12 lineouts.

No fear, no panic, no problem.

The worry over details of RG Snyman's injury will cast a shadow but it shouldn’t be allowed to overwhelm what was on show at Parc y Scarlets.

While there was much made of the fact that all five tries last weekend came from a grand total of about five yards of carries, yesterday's touchdowns covered the spectrum.

Midfield breaks, trucks up the middle, offloads, clever kicks, inch-perfect passing, skillful finishing and a pick and go for good measure.

"It’s playing what’s in front of you," former Munster and Ireland scrum-half Peter Stringer enthused afterwards.

"Growing up, when I was playing rugby, that’s what coaches would tell you: eyes up, if there’s space out wide then you go to it.

"Ben Healy was a guy who was able to distribute, the vision, the vocal guys on the edge who were able to communicate, these young guys made such an impression.

"After every turnover, after every scrum that they won, how close-knit they were and how much they enjoyed being there."

On how they weren’t disrupted by changing over two thirds of the side, the RTÉ analyst said: "There’s a game plan, there’s a structure that these guys would have trained to but just that ambition and that willingness to throw the ball around, on the back of some really good set-piece [was impressive].

"The scrum looked really good, they got a couple of scrum penalties, their defensive lineout – they didn’t allow Scarlets any attacking opportunities in the Munster half.

"All the basics, around the breakdown, when they had the ball it was a fraction quicker for [scrum-half Neil] Cronin to get the ball around.

"They got in their faces and didn’t allow them to play.

"You hear [man of the match] Chris Cloete talking about it: opportunities, you never know how many minutes you are going to get so you make the most of it, you enjoy it.

"It was interesting, a lot of guys playing with a smile on their face and they just enjoyed that experience.

"Scarlets were not up to the standards that they are normally at but credit to Munster. They deserve every ounce of what they got out of today in terms of physicality, attitude, defensively, everyone stepped up to the plate and it was a joy to watch."

Former Munster and Ireland captain Lenihan added: "It was an outstanding performance....a glimpse of the future perhaps."

On the other side, Scarlets, who face Leinster next Saturday at the RDS, couldn’t hide their disappointment.

Prop Rob Evans said: "Not acceptable from us, it’s embarrassing...we didn’t represent the jersey as we should have."
