Warriors coach Shaun Wane admits he made mistakes ahead of last year's semi-final and said of preparations this year.
I've tried to rest players and we've approached our training sessions in a different manner towards the back end of the season because it's a tough old year," he said.
"We've looked after the players a bit better and they were saying they felt really fresh going into the Leeds game.
"Going into the same game last year, they didn't feel fresh. We've fixed that and we can give ourselves a chance of being fresh next week and putting a performance in.
"At the end of the day, we're in two cup finals this year and we were fourth in the competition so it's been fairly good but it will be even better with a win next week."
