Munster head coach Johann Van Graan hailed his side's second-half display as they secured a 30-5 win over Castres Olympique in their Heineken Champions Cup clash at Thomond Park.

Caerphilly take on Castres in the Parker Pen Shield final hoping to become the first Welsh club to win a European trophy.

Alan Gaffney has named Denis Leamy instead of Jim Williams in his side to face Cearphilly on Friday night in the only change from last week's European Cup win over Perpignan.
