Former Dons midfielder Stephen Glass remains the favourite at 2/1 to succeed long-term boss Derek McInnes, who was relieved of his duties on Monday night.
Maresca – who is reportedly said to be Celtic’s top target as they continue their own search for a new manager – started as a 20/1 outsider with McBookie but has now risen above the likes of St Mirren boss Jim Goodwin and ex-Motherwell head coach Stephen Robinson.
The Italian has never held a manager's job before but is a highly regarded member of Pep Guardiola’s staff at the Etihad.
The 41-year-old had a long and varied playing career, representing the likes of Juventus, Milan, Sevilla, Olympiacos and West Bromich Albion along with several youth caps for his country.
He has had assistant jobs at Ascoli, Sevilla and West Ham United.
