Munster roared into the Heineken Cup semi-finals by crushing out-of-sorts Ospreys 43-9 at Thomond Park.
Led brilliantly by man of the match Paul Warwick, who notched a try and two beautiful drop goals, Munster showed why they are the reigning kings of European rugby with a performance of near perfection.
The Ospreys crumbled after Paul O'Connell's 55th-minute try, and the display from Munster suggested they will take some beating.
Munster scored four tries, two from centre Keith Earls, but could have added to that tally when running Ospreys ragged in a one-sided second half.
England's preparations for the Autumn International series were potentially dealt a further blow as Maro Itoje was forced to undergo an x-ray after Saracens' European victory over Scarlets on Saturday night.
