Leinster head coach Matt O'Connor has called for his team to bounce back against the Ospreys following their Heineken Cup exit.
The three-time European champions crashed out of this year's tournament with a defeat to Toulon last Sunday.
They remain however in first place in the RaboDirect Pro12 with the season drawing to a close, five points clear of Munster.
With stalwarts Brian O'Driscoll and Leo Cullen both retiring the chance to win one last major trophy is still on the cards.
O'Connor, in his first season since joining from Leicester Tigers, knows that the Ospreys will be fighting to save their own season with a win on Friday in Wales.
"We've played (Ospreys) enough to know enough about them. It's a huge game for them because if they lose they're probably out of it mathematically," said O'Connor.
"From that perspective they'll be doing everything they can to get the result and keep them in it.
"We've got to bounce back and we've got to make sure we fix the things that went wrong on Sunday.
"They're very hard to beat; they're hard to break down at home. They race off the line. They've got a good set piece. They've got a lot of Lions and Welsh internationals.
"We're under no illusions of how good they are at home. We're just going to make sure that we're better."
