What is clear is that Milne is determined not to lose his boss to his club's main rivals for second place.
Rangers appear to be moving to try and appoint McInnes as the new boss at Ibrox after considering their options following the sacking of Pedro Caixinha in October.
The Dons duo's talks come in the wake of Milne's decision to knock back a request from Rangers officials to hold discussions with the 46-year-old about becoming their new manager.
But with no shortage of interest in McLean from south of the border, Rangers will be hoping that they can finally lure McInnes to take one giant stride towards completing an exciting double deal that should improve their prospects both on the pitch and in the dugout.
Ferguson, 39, played alongside McInnes at Ibrox between 1995 and 2000, captaining the Light Blues to 5 Scottish Premier League, Scottish Cup and Scottish League Cup apiece, including a treble in 2002-03.
'I thought it would have died when McInnes made the statement recently to quash the rumours about Rangers, but it is back with a vengeance.
"He said: "[The situation] has not allowed the managers and players to get on with the job in hand, without having this cloud of speculation and having to face the same questions over and over again", said Miller.
The midfielder was dismissed by referee Willie Collum for following through on a tackle with Stevie May.
