Ulster target vital Heineken Cup win over Treviso

Ulster players Johann Muller, Darren Cave and Ruan Pienaar know they must beat a tough Treviso team on Ravenhill if they are to make a serious challenge for this season's Heineken Cup.

The Irish province, top of Pool 5 after wins over Leicester and Montpellier, will be fancied to see off the Italian club.

Skipper Muller described a home victory on Saturday as 'non-negotiable.'
