Ryan Giggs is the new favourite with bookmakers for the Sunderland job.
The Manchester United legend, who is keen to enter management having served as Louis van Gaal's assistant at Old Trafford, is now 1/8 with a number of bookmakers.
His appointment would be something of a surprise given the Black Cats have been targeting a manager with Championship experience.
Giggs himself is thought to be keen on waiting for an opportunity to manage in the Premier League and narrowly missed out on the Swansea City job last year, the South Wales outfit instead opting for Bob Bradley.
Sunderland's Chief Executive Martin Bain is stepping up the search for a new manager this week, with Derek McInnes in the frame.
Giggs replaced former Black Cats boss David Moyes as caretaker boss in 2014. The only game he lost was against Sunderland as a Seb Larsson volley edged the Black Cats closer to their greatest escape under Gus Poyet.
