Munster made it two wins from two UCL starts defeating Cardiff 23-20 at Thomond Park.
The win didn't come with a four-try bonus point while the Welsh side's 20 points total did as it comprised four unconverted tries.
But it proved the worth of Jack Crowley opting to kick a penalty and a drop-goal with his side's last two scores of the game, it proved to be the winning as opposed to the losing of the match.

"It's always great to win in Thomond," said the out-half after the game. "It is always great for us as a group to be able to come out here and represent everyone who showed up today despite the conditions and the storm in the country. It was important for us to put in a performance.
"Last week the starters put is in a really good position and we probably didn't see out the last 20 minutes the way we wanted, being clinical and disciplined. We were on it today for the most part and thankfully we won and put the learnings in."
Munster had handled the weather conditions well.
"I think that's down to the coaching staff having us prepped all week, going through the 'what ifs' about the conditions and the game plan. We were just prepared and whether it was first or second half we had a plan in place.
"We did have some time that was good but we probably didn't do it consistently through the 80 minutes so that's probably an improvement area for us but, overall, we are happy."
