Nacewa cautious ahead of star-studded Clermont crunch

Clermont’s Stade Marcel Michelin, with its high-banked tiers packed with vociferous supporters, has earned a reputation as European rugby’s most robust fortress but Isa Nacewa believes Leinster will bring their own 16th man to France next Sunday.

Joe Schmidt spent three seasons as assistant coach to Vern Cotter in the town perched atop the Massif Central and the Fijian suggested that will equate to “an extra man” when the two heavyweights take the first bell in this latest Heineken Cup meeting.

Signs are they might need it.
