Wigan Athletic chief executive Jonathan Jackson says they do have a shortlist of potential new managers ready after their relegation to League One.
The Latics' immediate return to the third tier was confirmed after their 1-0 loss at Reading in the Championship.
Graham Barrow has been interim manager since March when Warren Joyce left after four months in charge.
"We've been looking at a number of factors in getting the right person," Jackson told BBC Radio Manchester.
"We have a shortlist of people and we've been working on that. We'll take our time, but that is something that will probably be done at the end of May or early June - we know the kind of manager we're looking for.
"We were relegated two years ago, so we know what League One is all about and we start planning right now."
'I don't know the answer'
Ex-Latics midfielder Barrow, 62, took temporary charge of Wigan for a third time on 13 March when Wigan were four points from safety with nine games remaining.
He has since overseen two wins and a draw in his eight games in charge.
On a miserable afternoon at the Madejski Stadium it was also confirmed after the game that midfielder Shaun McDonald suffered a broken leg.
"I expected myself to do better because when I came years ago I managed to stop relegation into non-league," said Barrow.
"I was probably foolish enough to think I could stop this happening, but I haven't."
Asked if he will be at the club next season, he said: "I honestly don't know the answer to that, I hope so.
"I don't want a situation that has happened in the past a couple of times where I'm just around the place."
