Burnley chief executive Lee Hoos has ruled out a Turf Moor return for Owen Coyle following Eddie Howe's exit.
The Scot masterminded Burnley's promotion to the Premier League in 2009, but Hoos believes a return would not work.
"I just couldn't see how that one could happen," said Hoos.
Burnley are seeking a replacement for Howe, who left the club on Friday to return to Bournemouth.
"Obviously I wasn't there when the whole Owen Coyle saga happened," Hoos told BBC Radio Lancashire.
"But I got enough feedback to know that there was a very bitter aftertaste and I just couldn't see a way back for that one.
"It has to be the right person - the right man for right job at the right time."
