Clermont Auvergne steamrolled Exeter Chiefs in a 35-8, bonus-point victory at Sandy Park in the Champions Cup.
After being eliminated at the group stages last year, Franck Azéma's side made a statement of intent in this year's competition, in blowing the Chiefs away despite falling behind to a seventh minute Gareth Steenson penalty.
But Exeter were the architects of their own downfall, with Kai Horstmann and Steenson (twice) flying off the line and the visitors capitalised.
There was an element of fortune about Clermont's first try as Wesley Fofana's pass rebounded off Benjamin Kayser's head and back to him before Julien Bardy went over in the corner. Morgan Parra converted 24 minutes in.
They extended their lead four minutes later when a Parra box kick was gathered by Camille Lopez. Clermont recycled, and spread the ball left through Remi Lamerat, Fritz Lee and Nick Abendanon before Noa Nakaitaci strolled over for their second try. Patricio Fernandez converted for Clermont
A third followed before halftime when Camille Lopez side-stepped Steenson's missed tackle and drawing the defender he released Wesley Fofana to glide over. Parra converted for a 3-21 lead at the break.
Within three minutes of the restart, the game was over as a contest. Exeter missed tackles piled up as David Strettle broke down the right, and a flick inside to Lee allowed Abendanon to step inside for their fourth try.
Flip van der Merwe was sin-binned for the French side as Exeter laid siege to their try line but Clermont turned the ball over thanks to Parra's work at the breakdown. As the game lacked any fluidity, Fofana ran onto a Ludovic Radosavljevic pass to score a fifth try.
Sam Hill crossed in the final minute for a consolation try after replacement Henry Slade put him through, but they will need to dust themselves off before next weekend's trip to Ulster while Clermont face Bordeaux Begles at home.
