Their rich vein of end season form sees the Blues on an unbeaten six game run that has them in a European final and an eight point winning margin victory away from a place in the Magners League semi final.
In contrast Munster have won just one of their last four games with the biggest disappointment copming last time out with that defeat in San Sebastian.
Supporters will also be mindful that the last time Munster played Cardiff Blues immediately after a Heineken Cup semi final defeat was in 2004 when the Blues ran out 60-14 winners.
