The draw is as follows:

Semi-final 1:

Toulouse or Northampton Saints v Leicester Tigers or Munster

Semi-final 2:

Leinster Lions or Biarritz Olympique v Llanelli or Perpignan

So the draw for the semi-finals of the Heineken Cup have kept the possibility of an all Irish final at Lansdowne Road alive with Munster and Leinster drawn apart.
