Munster are the only former Heineken Cup winners through to the prestigious tournament semi-finals at the end of the month - Saracens, Toulon and ASM Clermont Auvergne each out to get their names on the trophy for the first time.
Former double champions Munster will clash with ASM Clermont Auvergne at Stade de La Mosson in Montpellier in the first of the high profile last four contests on Saturday, 27 April.
A day later Saracens will be back at Twickenham Stadium for their Sunday showdown with Toulon - Jonny Wilkinson booting the Top 14 pacesetters through with six penalty goals and a trademark drop goal at the death for a 21-15 home win over Leicester Tigers.
In the earlier Sunday quarter-final Munster booked a record-equalling 10th semi-final with an 18-12 victory over Harlequins at The Twickenham Stoop - their fourth quarter-final win on the road - with Ronan O'Gara contributing all their points with six penalty goals.
