Exeter Chiefs overcame a shaky start to power past Lyon and set up a Heineken Champions Cup quarter-final against Leinster with a 47-25 victory at Sandy Park.

By the eighth minute Rob Baxter's European champions had slipped 14-0 behind but through a pair of tries by England lock and man of the match Jonny Hill they clawed their way back into contention.

Further touch downs by Tom O'Flaherty and Ollie Devoto helped them into a 26-20 half-time lead and then the floodgates opened as Dave Ewers, Olly Woodburn and a penalty try swept them clear.

It was a far from vintage display from the error-prone double winners, who welcomed back their stars from England, Scotland and Wales after two months on Six Nations duty and looked disjointed as a result.

Leinster will see vulnerabilities ahead of next weekend's heavyweight Sandy Park showdown, but Exeter's strongest team will have benefited from a tough examination by Lyon.

French heavyweights Clermont Auvergne floored Wasps with the final play of a pulsating Heineken Champions Cup clash to win 27-25 at the Ricoh Arena.

Clermont captain Camille Lopez converted full-back Kotaro Matsushima's try with the game's last kick, and Wasps' hopes of reaching the quarter-finals dashed in dramatic fashion.

Up until that crushing moment for Wasps, it had been the Paolo Odogwu show.

He delivered an emphatic reminder of his ability to watching England boss Eddie Jones, scoring a try after just five minutes and narrowly missing out on a second one just before half-time.

On his first start since January 8 after being selected for England's Guinness Six Nations squad, but not playing a minute of the campaign, Odogwu was outstanding.

Odogwu's fellow wing Josh Bassett also touched down, as did prop Ben Harris, while fly-half Jacob Umaga kicked two penalties and two conversions.

Scrum-half Sebastien Bezy and prop Peni Ravai scored Clermont's tries before Matsushima struck, with Lopez booting 10 points and Tim Nanai-Williams converting Bezy's touchdown.
