Ospreys will be without injured Wales stars Gavin Henson and Lee Byrne for the daunting trip to reigning champions Munster in the quarter-finals of the Heineken Cup tomorrow.
Ireland wing Tommy Bowe has been switched to full-back in Byrne's absence, while Sonny Parker and Andrew Bishop form the centre pairing as the Welsh region look to go one step further than last season when they were dumped out of Europe by Saracens.
Ospreys head coach Sean Holley said: "We have a group of players with an appetite to go and prove they can produce the goods on such a big stage.
"We are just concentrating on ourselves, and I hope Ireland's Grand Slam will put more pressure on them (Munster)."
James Haskell admits that his six-month lay-off with a toe injury has been the most frustrating period of his career and says he is still dealing with regular pain on his quest to return to full fitness.
