Munster might have used up a fair portion of their luck in Cardiff where the home side had no-one but themselves to blame for not, at least tying the game with the last move of the match not to mention the fact that it required the TMO to adjudicate on two occasions about possible Blues touchdowns.
Replays showed he ruled correctly and there was no element of luck about the tackle perpetrated by Denis Hurley that denied Alex Cuthbert at the start of the game, Hurley again putting in a monster hit late in the game to prevent a certain score under his posts.
A feature of that game was what Tommy O'Donnell described as 'massive defensive performance ' and he also made reference to the 'phenomenal kicking display' from out-half Ian Keatley.
Tonight Munster are going to have to give a reprise of that defensive display while hoping to play a little more ball in their opponents half rather than rely solely on Keatley to harvest their points.
