And what makes their game in the Stadio di Monigo all the more significant is the almost certainty that leaders Leinster and second placed Ospreys will continue on their winning ways, Leinster at home to Scarlets and Ospreys at home to Aironi.
Even at this stage with eight games for them to go, only an implosion of massive proportions will deny Leinster a 'home' semi but Ospreys are far from home 'n hosed in that regard. However, were they to win with maximum points this weekend, it could leave the chasing pack looking for away semi final trips. And going to places they'd rather not.
Munster complete their preparations this morning in CIT and name their squad afterwards.
That squad will check into Cork and Shannon Airports tomorrow morning in the wee hours and head for London Stanstead before continuing on to Treviso.
