Munster face an Edinburgh side who were trounced at home in their opening game by Saracens but it would seem very naive to gauge Edinburgh's ability on that one performance.

"They'll come to Thomond Park, hopefully thinking they're coming in under the radar after that loss" - Rob Penney

Ahead of the game coach Rob Penney said: "They did some really good things against Saracens.

"If you look at that game closely you'd be remiss to disregard their display totally. Because they did some really good things."

"They got, and I know it's very un-Edinburgh like, but they got beaten up a few times at some breakdown situations and a couple of times at set-piece."

"So undoubtedly they'll be doing some work in that area. And they'll come to Thomond Park, hopefully thinking they're coming in under the radar after that loss.

"But we're certainly doing as much diligent research as we've done in any other game to ensure that we're as prepared as we can be. And I think there's two sides hurting a bit, it could be fireworks."
