But while Heaslip is all too aware of the challenge the big-spending Welsh region after scooping the man-of-the-match crown against Munster he is already settting his sights on repeating the trick this weekend.

“We have a huge test and it will be another massive battle up front,” said the Ireland No 8. “The Ospreys have an array of talent out wide so we will have to up our levels again.

“While it’s humbling and I’m extremely grateful to receive the award, I hope it won’t be the last one for this season.”

Leinster squad to face Ospreys:

Leinster (from): Shaun Berne, Gordon D’Arcy, Girvan Dempsey, Shane Horgan, Rob Kearney, Fergus McFadden, Isa Nacewa, Paul O’Donohoe, Brian O’Driscoll, Eoin Reddan, Jonathan Sexton; John Fogarty, Cian Healy, Jamie Heaslip, Nathan Hines, Trevor Hogan, Shane Jennings, Stephen Keogh, Kevin McLaughlin, Sean O’Brien, Malcolm O’Kelly, Mike Ross, Richardt Strauss, CJ van der Linde, Stan Wright.
