Clermont Auvergne warmed up for their European opener by maintaining their excellent start to the Top 14 with a convincing 38-13 home win over Bayonne.

The star-studded outfit top the French league and will pose a real threat to Leicester Tigers and the Ospreys in Pool 3.

France scrum-half Morgan Parra and Scotland flanker Jason White have signed on as Clermont bid to reach the quarter-finals for the first time since 2002.

Viadana, in only their fourth season in Europe’s premier competition, will aim to finish off the bottom of the pool table for the first time.
