The Foxes defeated Paul Lambert's side courtesy of a Paul Konchesky goal in first-half stoppage-time that saw them extend their unbeaten run in all competitions to four games.
Those three points will prove vital as it now means Leicester are just three points adrift of Premier League safety in a so-far tight relegation battle. However, Pearson chose to focus on the referee’s failure to point to the spot on two occasions and how that could have ultimately cost his side all three points.
“It could have been more than 1-0 today,” he told Sky Sports.
“It was unfortunate today that we weren’t awarded at least one, [Leonardo] Ulloa’s in the second half and Dean Hammond in the first are both decisions that haven’t gone our way.”
The latter stages of the game were marred by an altercation between Leicester midfielder Matty James and Aston Villa defender Ciaran Clark, following the former’s challenge on Villa’s young defender Jores Okore.
Both players ultimately received a red card for the incident but Pearson refused to comment on the issue until he had seen the referee’s report on the game.
“I’m not making any comment on anything regarding that situation in the game at this moment in time,” he added.
“I’ve seen it, I’ve got my own opinion on what happened and I’d like to see what is in the report from the officials and I’ll wait to see how things are reported from people like yourselves.”
