Blues No.8 Xavier Rush commented, "Certainly Leinster is a big game for us, but obviously the first hurdle is the Ulster match and they are expecting a packed crowd so it will be a very tough away game. The Leinster match at home in the Millennium Stadium next weekend will also be a massive game for us.
"I've only ever watched a game at the Millennium Stadium and that was Wales v the All Blacks just before Christmas and the atmosphere there was probably the best I've ever experienced at a rugby match.
"Hopefully if we can get enough people there it'll make for a great occasion. The way the guys have been playing and the way Leinster play I think it'll be a cracking game of rugby, so hopefully people can come along on Sunday and it will be a really good spectacle."
Marc Stcherbina, the Australian centre added: "I'm looking forward to the game as I've never played in Millennium Stadium, hopefully I'll get a chance to run out next week in front of a really good crowd as well. The first match I saw there was the 1999 Rugby World Cup final where the unbeatable Australian team won the World Cup for the second time.
"It was a great atmosphere, but it all changed when Wales beat Australia there, which again was a fantastic game and atmosphere. It's a fantastic venue and a big game for us and hopefully all the crowd and supporters will get behind us.
"The supporters have been wonderful this season already and we're just happy that we've been able to return the favour to the crowd in our recent victories at home and we aim to do the same thing at the Millennium Sstadium."
