Alex McLeish makes stunning revelation about Rangers job
McLeish was boss between 2001 and 2006, winning the domestic treble in 2003, among other honours.
He was invited by the Gers board to discuss the position vacated by Mark Warburton in February, with the club eventually opting for Pedro Caixinha.
Asked how close he was to becoming the Light Blues boss for a second time, he said: "I did speak to them and I said that if they were to come back and offer me it, I would like to speak further.
"It was a very casual chat. It wasn't what I would call an interview, it was meeting old friends again and seeing where they were going with the club.
