I doubt Smith would walk out on Scotland, especially since he’s doing an amazing job there. Plus he’s been there/done that with Rangers before.

Souness would be interesting, but I doubt the fans would want him after walking out in 1991 with 3 games left in the season. And his spell at Newcastle wasn’t exactly a glorious success.

Of the other two I’d go for Terry Butcher, being a former captain and all, but would he leave Sydney for Ibrox?
