Derek McInnes has emerged as the new favourite for the Sunderland managerial vacancy.
The Aberdeen boss has built a strong reputation north of the border having led Aberdeen to three consecutive second place finishes in the top tier of Scottish football.
He has managed it this year despite the return of Rangers to the top flight, and also won the Scottish League with the Dandies in 2014.
They face Celtic in the Scottish Cup final this coming Saturday.
McInnes has worked as a manager in the Championship once before, taking over Bristol City boss in 2011. An eight game unbeaten run saw them escape the drop but he left a year later with the team four points adrift of safety.
He also managed St Johnstone between 2011 and 2013, winning the Scottish First Division.
Walter Smith, said to have offered advice to Black Cats Chief Executive Martin Bain on the appointment, is a firm admirer, and backed him to take the Rangers job after Mark Warburton's departure in March.
Rangers instead went for Pedro Caixinha.
McInnes is the 6/4 favourite with bookmakers, although Sunderland are considering a number of names for the post.
Ellis Short promised a 'period of reflection' following David Moyes' resignation on Monday morning and an appointment is not thought to be imminent.
Previous favourites Nigel Pearson and Kevin Phillips are beginning to drift, with Pearson thought to be on a three man shortlist for the currently vacant Middlesbrough job. Garry Monk, an early favourite among fans, is set to sign a new deal to keep him at Elland Road on Friday.
