Pearson said: "There is a long way to go but we have got a bit of momentum behind us. We are in a good run of form but complacency is not something we can allow to set in.
"We have got a number of quality players for this level and maybe for the level above. I know I have a decent squad at my disposal but ultimately it's about performing on match days."
Lloyd Dyer's late winner kept the Foxes top of the table but with no game next weekend we could lose that place (temporarily).
