It’s a doubly tough ask for Ulster and Munster if they are to get through to the Heineken Cup final in the Aviva Stadium in May as Toulon and Clermont were kept apart in the semi-final draw.
The quarter finals draw sees both Irish teams away in London in the quarters with Munster facing Harlequins and Ulster going to Saracens.
Leinster meanwhile will face Gloucester or Biarritz if they get through their trip to London Wasps in the Amlin Cup.
