Mike Phillips crossed for the Ospreys while Munster prop Tony Buckley and Ireland centre Keith Earls were both on the scoresheet in their losing cause.

In the corresponding fixture a week previously the Irish region came out on top 22-16 and Leamy – who will be looking to be part of Ireland's RBS 6 Nations campaign having played in three of their four autumn clashes – was less than impressed with the turnaround in fortunes.

“From the off, our scrum was definitely second best,” said Leamy – whose side sit second in Pool Three, two points shy of leaders Toulon. “It’s a huge area in rugby union and it was one area we fell down in.

“We can have no complaints. I think the ref could see a lot and he took a lot of decisions against us and it hurt us badly.

“Everyone will look at the frontrow but we’ve got to take this on as a forward pack, look at ourselves and be a lot better than we were today. If you went through our dressingroom, there’s fellas just absolutely gutted in there.”
