Munster will launch their defence of the Heineken Cup with a challenging trip to former double winners Leicester Tigers in a Pool 4 clash on October 22.

The European Champions will follow that up with home tie against Bourgoin, and then back to back games against Cardiff Blues.

Last season's beaten semi-finalists Leinster are at home on match day one to Gloucester before they travel to Edinburgh and then take on Agen home and away.

In pool five, Ulster begin at home to Toulouse, they go to Llanelli six days later and then face London Irish home and away.
