The key battle
David Wallace v MARTY HOLAH
Essentially the entire back-row will be the key to this contest, not only in collisions, but specifically how each side manages at the breakdown beneath the capricious eyes of Monsieur Berdos, the ref who so enraged Saracens' departing coach Brendan Venter in round two.
The veteran Wallace returned to a semblance of old form towards the end of the November Series and will be looking forward to facing off with the visitors' best back-rower Holah, who yesterday successfully appealed his two-week ban and will take his place in the Thomond Park showdown.
Match betting: Munster are 10/11 to win by at least eight points and deny the visitors a crucial bonus point.
Formguide: Munster WWWWLLWWWWWLW
Stat: Ronan O'Gara's leading total of 1,165 points in Heineken Cup history puts him way ahead of the chasing pack.
