The Villains look set to be relegated to the Championship this season following a disastrous campaign.
They are currently bottom of the table and 12 points from safety having managed just three wins all season.
Many believe they could be set for further disappointment in the Championship next season given how poor they have been this season.
Pleat though, believes that they may return to the top flight in the next two or three years.
"The board have made so many mistakes at Aston Villa but they are getting new people on the board who know English football,” he told BBC Sport.
"Their transfer policy needs to improve, but I expect to see Villa back in the Premier League in two or three years' time. Next season, Aston Villa are going to have to look at recruiting the very best Championship players.”
“They might be able to lure them to Villa Park, because they can afford the salaries. So any new manager has to know players at that level."
Who Aston Villa appoint as their next manager is arguably crucial to their hopes in the Championship next season.
Given how tough the division is, they will need a manager who is accustomed to that and knows how to survive a tough campaign.
That is why the likes of Mick McCarthy and Nigel Pearson must be high among their potential targets, with both having enjoyed success in that league before now.
More than that, they know the types of players required and that may put them ahead of David Moyes at this stage.
