WRU AUDIO: Scott Quinnell looks ahead to the Heineken quarters
The Blues beat Bristol 17-0 on Sunday to win Pool 3 and book a quarter-final trip to three times champions Toulouse, while the Ospreys' 28-21 triumph in Bourgoin meant they earned a trip to number one seeds Saracens in the last eight.
The draw for the semi-finals, which will take place on April 26th / 27th , is as follows:
London Irish or Perpignan v Toulouse or Cardiff Blues
Saracens or Ospreys v Gloucester or Munster.
This draw means that their could be an all-Welsh final, or an all-English final for the second year running. The winners of the 2006 Heineken Cup final in Cardiff, Munster, could return to the Millennium Stadium for a third final, while there can only be one French finalist - Perpignan or Toulouse.
