"We're coming up against tough opposition in Wigan who are well drilled and well coached. I'm just enjoying the moment and the build up to my last game.
"I've been very blessed in my career, especially here at Leeds. Win or lose this weekend, I'll still be satisfied with what I've done."
The Rhinos are also bidding farewell to former Great Britain and England international pair Jamie Peacock and Kevin Sinfield, who will join Leuluai in making their final appearance for the club.
"I couldn't think of a better way to finish than with those two," he said.
"We've had some great times over the nine years I've been at the club.
"I think I'd feel a bit lonely if I was bowing out by myself. Going out with the company of those two has definitely made it much easier."
