David Strettle and Chris Ashton each scored two tries as Saracens claimed a bonus-point 30-23 win over Clermont in their European Champions Cup match at Allianz Park on Saturday.

Zac Guildford went over twice for Clermont, who will feel they missed a great opportunity after dominating large periods of the game.

Meanwhile, Harlequins were made to work hard for a 25-9 victory over Castres at The Stoop in the first ever Champions Cup match on Friday night.

On Saturday, Ian Keatley's last-gasp drop goal handed Munster a 27-26 win away at Sale, Mark Bennett scored two tries as the Glasgow Warriors cruised to a bonus-point 37-10 victory over Bath, Leicester were forced to hold off a ferocious Ulster fightback on their way to a 25-18 win at Welford Road, and Marc Andreu's late try denied Northampton a bonus point in a 20-11 win.
