The Millers, sat in third place in League Two, travel to Adams Park to face the second-placed Chairboys having suffered just one defeat in their last nine games - and Moore, in positive mood, insists he is going to get a win.
"It's a massive game. We have been on a tremendous run and if we do the same again we will cement our place in the top three," he told Press Association Sport.
"If we can get the win over Wycombe on Saturday it will take us above them and we still have the game in hand.
"I think it will be an open game, we're not a side that will go and put nine men behind the ball. We're going to go on the front foot and if we do that I think it will be wide open and we'll win the game."
Meanwhile, midfielder Grant Darley has joined Ossett on a one-month loan deal. The 19-year-old, who signed a new six-month deal with the Millers at the start of this week, links up with the Evo-Stik Premier Division side in order to gain more first-team experience and improve his match fitness.
