St Johnstone are still seeking a new manager after talks with Sligo Rovers' Paul Cook broke down.
The Scottish Premier League club's chairman, Geoff Brown, told BBC Scotland that they could not agree personal terms.
And the Perth club are now considering other candidates.
Brown says the failure to agree terms was linked to the 44-year-old Englishman not wanting to uproot his family.
And he dismissed reports suggesting that Cook would not be able to bring his assistant manager with him to McDiarmid Park.
"We didn't even talk about that issue," said Brown.
St Johnstone are seeking a new manager after Derek McInnes moved to Bristol City last week and Brown stressed that the parameters for considering a new manager were different this time round.
"Both Owen Coyle and Derek McInnes came to us when we were in the First Division and looking for promotion," he said.
"We now need someone who can keep us stable where we are in the Premier League."
Youth team coach Alec Cleland, assisted by midfielder Jody Morris, will continue to be in temporary charge as the squad prepares for Saturday's game against St Mirren at McDiarmid Park.
Cook, who has been in charge at the Showgrounds since 2007 following a short stint with Conference side Southport, had become St Johnstone's number one target.
Bookmakers' odds on him taking over in Perth were slashed as he arrived in Scotland for talks having been recommended by former Stockport County team-mate McInnes.
However, Sligo have announced on their website: "After giving permission to speak to Scottish Premier League side St Johnstone in recent days, Cook will stay in charge at the Showgrounds and we look forward to final matches of the season."
Sligo are in the FAI Cup final for the third season in a row, having won the trophy along with the League Cup last season, and sit second in the League of Ireland this term.
St Johnstone now turn their attention to other candidates, although Brown has already ruled out former Chelsea midfielder Morris as the chairman does not want a player-manager and the 32-year-old insists he wants to continue playing.
Former Rangers defender Cleland confirmed on Saturday that he wished to be considered for the job on a permanent basis.
