Racing Metro's 15-3 win over Edinburgh in Murrayfield on Friday keeps their hopes very much alive and they lead the Pool by 2 points. So whoever takes the spoils today in Vicarage Road will go into the New Year with their destiny very much in their own hands.
Saracens rarely if ever sell out their home ground but the talk here this morning is that we are heading for a sell out as the English based Munster supporters rally to the cause.
And for the English side it seems very much a case of 'putting a wrong right', after a Thomond Park Stadium defeat that owed much to their own below par performance with little credit to Munster for the part they played.
And it was that attitude Rob Penney wasn't inclined to discourage at the post match media briefing believing it might allow Munster slip in under the radar.
However. he's canny enough to know that once Saracens do notice the blip on their screen, his team will be in for another torrid examination. He has had to re-adjust his side with the injury to Keith Earls but is blessed of course to have a quality player like Casey Laulala to come in.
Once again the old heads, Donnacha O'Callaghan and Ronan O'Gara will be asked to draw from their deep well of experience while James Coughlan, winning his 100th cap can be relied on to deliver his usual compelling shift.
It might be too that the young bloods will have drawn huge confidence from what they achieved in Limerick last week. And if they can, then Munster could make their supporter's journey well worthwhile.
