Despite a comprehensive 40-17 win at Montpellier last time out, Ulster hooker Rob Herring wants a much sharper breakdown effort when the province visit Clermont in Saturday's Challenge Cup quarter-final.

"I think there were things throughout the Montpellier game that weren’t good enough, the breakdown being one of them. That’s been a key thing over the last few weeks. Clermont are one of the best jackal teams in the TOP 14 so I think that’s something we have to get right this weekend."
