Despite repeatedly stating he has no interest in a return to the post, Rangers boss Walter Smith is likely to be approached, along with Dundee United's Craig Levein, who has been reluctant to address the speculation.
"We'll be looking to identify other people ourselves," added Smith. "Along the way, we would have to find out whether they have an interest in it.
"We're looking for someone with experience but I won't react to any names. I think it's totally unfair if I speak about anyone in a positive or negative manner.
"It will be someone with a good reputation, someone who we feel can take the team forward and take Scottish football forward."
