Leicester were on cloud nine after a sensational 5-3 Premier League victory over Manchester United two months ago, but have been brought back down to earth with a bang since then.
The Midlands outfit have picked up only one point in their six top-flight matches following victory over United and that was from a 2-2 home draw against bottom club Burnley.
A lack of goals has been Leicester's downfall, with Pearson's side scoring only finding the net against the Lancastrians since taking advantage of the frailties in United's defence.
Leicester have slipped into the relegation zone as a result of their dismal run and Pearson knows they must stop the rot ahead of Saturday's clash with Gus Poyet's side at the King Power Stadium.
He said: "We do need to get back to winning ways to reignite the confidence, that's a very important factor of how we go about the game.
"Ultimately we want to get the right result regardless of how we play, it's about finding a way to get the right result.
"They are well organised defensively. We need to be patient, play our own game and that’s what we'll endeavour to do. They are a better side than people give them credit for, Gus will know we need a result and will be expecting a tough game."
Sunderland striker Steven Fletcher is expected to start after recovering from a knock sustained during Scotland's Euro 2016 qualifying win over Republic of Ireland last Friday.
The Leicester manager said: "He (Fletcher) looks fit and is a very dangerous player in and around the box, we must make sure concentration is such that we are able to deal with their threats.
"For the most part this season we've defended pretty well, where we've been undone is quality on their part. We have got to turn our run around by performing ourselves, and create opportunity for our attacking players."
