Scrum V: 'Showboating' backfires on Treviso's Henry Senioli

Scrum V shines the spotlight on the moment Treviso scrum-half Henry Senioli taunted Scarlets centre Scott Williams during the crucial Pro12 game in Italy.

It should have been an easy try, but Wales international Williams makes Senioli pay for his showboating.

Former Wales internationals Martyn Williams and Jonathan Davies are not impressed.
