Leicester host Swansea on Saturday just three points from safety after back-to-back wins and Pearson is deperate for his side not to lose their focus.
He said: “I’m very wary of people flipping the emphasis. Our future is in our own hands and if we go into the last game with that we have given ourselves a realistic chance.
“We need to make sure our own run-in is what we want it to be. It’s helpful that other teams are being dragged into it. People are continually adjusting the form table and their predictions.
“We can’t get involved in anything apart from being involved in our own games that may change people’s perceptions. It’s great when results go your way but they only help if you’ve done your own job.
“It’s important for us to be in touch. One of the potential problems we have to deal with is people are now overly optimistic.”
