The Rhinos beat Hull 32-20 on Sunday, but Friday’s re-match is a fresh start for Leuluai.
“It won’t matter too much that we’ve played them on Sunday and then again on Friday night, it will be a different game especially with it being in the Challenge Cup,” he said.
“We’ve been a bit shaky in the league recently with a few dropped points, but we’re looking to go out there and get our structures right and progress to the next stage.
“I’ve had about three months off with a shoulder injury which has been frustrating. I’ve played a couple of games now so I’m just looking to get back on the horse and get a consistent run of games.”
The 37-year-old veteran front-rower would also like to end his time at Leeds with one more trophy to add to the collection.
“It would be a dream finish to win some more silverware in my final year at Leeds,” he said.
“Whatever happens, I’ve been quite lucky to have such a great career at Leeds to win so much in a great team.
“It was a relief to get the win at Wembley last year. We’ve won the Super League title five times since I’ve been here so it was good to get the monkey off the back with the Challenge Cup after losing three finals in a row.”
