Alex McLeish has indicated he would jump at the chance to return to Rangers.
The Scottish club are searching for a new boss after Mark Warburton's dramatic departure as manager on Friday night.
Graeme Murty was placed in charge of the team for Sunday's William Hill Scottish Cup fifth-round tie against Morton, but the out-of-work McLeish has emerged as the front-runner to take the Ibrox job.
McLeish, who won two league titles in a five-year spell as Rangers manager from 2001 to 2006 - including the domestic treble in 2003 - admitted he would find it hard to turn down the post, should it be offered.
"There is a lot of speculation, but at the moment there is nothing I can update you on," he told Sky Sports, ahead of Gers' 2-1 win over Morton.
"I am a Rangers man, you have to keep that in consideration, and when you get asked to come to club like this, it is a hard decision to turn that down.
"If they come and they want to speak to me, I can only take it from there. I need to wait and see if Rangers want to talk to me first."
