A late Tommy O'Brien try wraps up an ultimately comprehensive bonus-point win for Leinster at Stade Marcel-Michelin.

Clermont led 16-15 at half-time but Leinster's power and big-game experience told during a dominant second-half display.

In the other 13:00 BST kick-off, South African side Bulls are in control against French club Stade Francais.

Cheswill Jooste went over for the hosts after just 20 seconds and they have scored two further tries in the first half.

Stade Francais have replied with a couple of penalties but they trail by 15 points at the interval.

Bath, Northampton, Cardiff and Montpellier are also in this pool.

Jamie Dobie is some player and he shows all his class with this finish.

Sione Tuipulotu starts the attack with a powerful carry and the visitors then go wide to their electric little winger.

He bounces off a tackle, keeps himself inside the whitewash and dots down in the corner.

George Horne splits the posts from a tight angle and Warriors lead by six.

Alex Sanderson makes five changes to the Sale side that beat Harlequins last weekend.

Tomas Francis makes his first start for the club, while flanker Ben Curry features from the start for the first time this term.

England winger Tom Roebuck is back from a calf strain, Rekeiti Ma’asi-White returns after a knee problem and Luke Cowan-Dickie replaces Nathan Jibulu at hooker.

Meanwhile, Glasgow have made eight changes, including first appearances of the season for captain Kyle Steyn, prop Zander Fagerson and lock Alex Craig.

Ruwald van der Merwe makes his club debut at number eight having signed from Pumas in the summer.

Only Nathan McBeth, Scott Cummings and Rory Darge retain their places in the forward pack that started the URC win over Connacht last time out as Seb Stephen starts at hooker and the fit-again Euan Ferrie comes into the back row.

Head coach Franco Smith sticks with the half-back pairing of George Horne and Dan Lancaster, with Stafford McDowall partnering Sione Tuipulotu in the centres.

Steyn joins Jamie Dobie and Kyle Rowe in a potent-looking back three.
