Monster is in Wales for the PRO14 game starting this weekend.
Johan van Grann faces a big challenge from home against Scarlett, who defeated the Reds in their last clash at this venue.
Munster wants to continue the 100% start of the Irish teams into the new season after the record victories of Leinster and Ulster on Friday night.
Leinster beat the Dragons 35-5 at the RDS in Dublin, while Ulster defeated Bennett 35-24 at Kingspan Stadium.
The bookies are struggling to split the Scarlett and the Monster for this afternoon’s game, and we’ll get to the very next match, which takes place at 3pm.
