Pre-Match Quotes: Shaun Berne (Leinster) - "Even though we won last time out against Cardiff at the RDS, Sunday's game will be a real test for us coming, as it does, when so many of our players are away on international duty.
"At this time of year, the squad's resources are stretched, but with a few of the international players returning, we're in a good frame of mind ahead of the game.
"Having played Cardiff twice before with Bath, you know what to expect against them, or any Welsh side for that matter - pride, physicality and a high skill level.
"They're a passionate rugby playing people and rugby's pretty much a national past-time over there.
"From a player's perspective it's a great place to play and with the new stadium and a good surface to play on it should make for an exciting game.
"Even though we have big games coming up this month in the Magners League, we'll take it one game at a time and we're not looking beyond this challenge.
"For those of us who want to play regularly in the side as we approach the business end of the season, Sunday will present an opportunity to stake a claim.
"As well as the pride in representing Leinster, the Ireland players who have been released this week will no doubt look to Jonathan Sexton's example last month when a good showing against the Scarlets helped him earn a spot in the win over England last weekend.
"It's imperative that we begin well and look to dominate the key exchanges and if we manage that, we'll need to be playing at the top of our game to get the win."
David Young (Cardiff Blues) - "Our last three home matches in the Magners League are against Irish opposition, starting with Leinster, followed by Ulster at the end of the month and Munster in May.
"We know all of these matches will be tough challenges with Irish rugby on a high following last season's achievements. So we know we have a difficult run in, starting with Sunday's game.
"While our cup form has been good this season, our Magners League form has not been up to standard.
"With only a few games left in the league and important qualification for the Heineken Cup at stake, every point is important for us.
"Obviously we were all pleased with our last league performance and result with our win up in Glasgow.
We completely dominated the game and with 10 minutes left we were 30-0 up, having scored three tries.
"Our record against Glasgow has not been brilliant, having not won there since 2005, so perhaps it is greedy to have wanted a bonus point."
