Munster fans will be passing a keen eye over the events in Pool 3 this afternoon.
Declan Kidney's quarter final opponents will be decided this evening with the games in Pool 3 having a huge impact.
If Cardiff beat Bristol at the Memorial Ground, Munster will almost certainly face Gloucester in the last eight.
A win for Bristol could mean a trip to the south of France to play favourites Toulouse in the quarters.
The other Pool 3 game sees Harlequins face Stade Francais, and both kick off at 3pm.
