CARDIFF Blues have the most favourable draw out of the three Welsh regions in the Heineken Cup with London Irish, Edinburgh and Racing Metro in their group.

The Scarlets have been handed a 'group of death' having to face Magners League champions Munster, this year’s Heineken Cup finalists Northampton and French side Castres.

Things aren’t much easier for the Ospreys who have to clash with their 2010 nemesis Biarritz, Aviva Premiership champions Saracens as well as Benetton Treviso.

Newport Gwent Dragons have to wait until a week on Thursday to find out their opponents in Europe next season when the Amlin Challenge Cup draw is made.

Draw: Pool 1: Munster, Northampton, SCARLETS, Castres

Pool 2: CARDIFF BLUES, London Irish, Edinburgh, Racing Metro

Pool 3: Leinster, Bath, Glasgow, Montpellier

Pool 4: Leicester, Clermont Auvergne, Ulster, Aironi

Pool 5: Biarritz, OSPREYS, Saracens, Treviso

Pool 6: Toulouse, Harlequins, Gloucester, Connacht
