Northampton Saints lock Samu Manoa has talked up the "massive" challenge of taking on three-time champions Leinster this weekend.
The Irish side broke Northampton hearts in 2011 when they came back to win their second Heineken Cup title.
Saints then missed out on a spot in the last eight of last year's competition, leaving Jim Mallinder's team with plenty of unfinished business in Europe.
Northampton are currently on a six-match unbeaten run in the Aviva Premiership ahead of facing the Pro12 champions.
"The Heineken Cup is just another level of rugby and the boys are looking forward to it," said Manoa.
"The boys are excited when the Heineken Cup comes around and everybody has got to bring their A-game to the table.
"We will worry about Leinster when Leinster come. It is massive for the club and for us boys. We were upset about how it turned out last year.
"They have got a good squad and we have got a good squad too, so there is going to be a clash."
Reflecting on his personal form this season after winning the Premiership Player of the Month award for October, Manoa admits he still has work to do.
"There is a lot of stuff I can improve on but I am playing pretty well right now. I have just got to keep up with it," added Manoa.
"Life is good and I am just taking it day by day. Every day is just another day in paradise."
