Pearson told reporters: "It is about what has been done over the last two-and-a-half-years. One of the biggest jobs when you take over a club is to get rid of the rubbish that is here. The players who don't have any value, whether that is financially or value to the team.
"That is the hardest job of any manager these days to offload the players you don't want. I still keep being reminded of how much money we have spent but I don't remember spending a lot of money since I have been here.
"We have certainly improved the squad hugely and we have trimmed it down and we are a better side because of it. That will be how we try and take the club forward."
Leicester are nine points clear of second-place Burnley as they look to cap off their season by winning the Championship title.
