Champions Cup round-up: Exeter edge past Montpellier, Wasps dominate Harlequins and La Rochelle seal win against Ulster

Montpellier 24-27 Exeter Chiefs
Exeter Chiefs made it back-to-back Champions Cup wins as they claimed a famous 27-24 victory away to French giants Montpellier.
Don Armand scored a try in each half while centre Ian Whitten also added a try as Gareth Steenson kicked three conversions and two penalties for the best European result in Exeter's history.
Nemani Nadolo crossed twice for Montpellier and Joe Tomane and Benoit Paillaugue also added scores, but it was not enough to stop Rob Baxter's men from celebrating.
The home side secured two points for scoring four tries and finishing within seven of Exeter, but it is the English outfit and Leinster who are both unbeaten in Pool Three.
Wasps 41-10 Harlequins
Nathan Hughes terrorised Harlequins as Wasps swept aside their Aviva Premiership rivals with a 41-10 bonus-point victory in a Champions Cup match in Coventry.
The England number eight spearheaded Wasps' five-try assault on Quins as Dai Young's men ended a miserable run of five straight defeats in style at the Ricoh Arena.
Joe Marler was perhaps fortunate to avoid a red card for a forearm smash to Will Rowlands' midriff, another unsavoury disciplinary incident for the England prop.
La Rochelle 41-17 Ulster
La Rochelle maintained a winning start to their debut Champions Cup campaign by following victory at Harlequins with a 41-17 home win over Ulster in Pool One.
The team that led the regular Top 14 last season, and who only lost once at Stade Marcel Deflandre, physically dominated the Irish province after a tense first half that saw the visitors hold their hosts to 13-10.
But once the teams changed ends it was one-way traffic and La Rochelle ran in four tries to bag the bonus point and lay down a marker ahead of their back-to-back clashes with Wasps in December.
