Victory over Sheffield Wednesday alone will not be enough to guarantee promotion for Pearson's men - though it could come on Saturday if both QPR and Derby subsequently fail to win.
Despite the mathematics Leicester are effectively assured of ending their 10-year absence from the top tier after moving 16 points clear of third-placed QPR with last weekend's win at Burnley.
And Pearson is convinced his current players have every chance of holding their own at a higher level after comfortably seeing off the best the Sky Bet Championship has to offer.
Pearson told the Leicester Mercury: "We have some quality at this level and I believe a lot of our players are capable of making the step up when we achieve that.
"It is all right having good players but they have to be the right sort. They have to have the same goals and when things get tough, they have to be prepared to keep those values going.
"You can't build a team overnight. It has taken time to build a squad of players good enough."
Leicester will be without Jamie Vardy who injured his groin in the win at Burnley, while Zoumana Bakayogo is still out.
