Brentford manager Thomas Frank has been cut from 40/1 to 16/1 to become the next Manchester United boss.
It follows speculation he is several of the club's board's preferred candidate for the role.
The Dane took charge of the Bees in the 2018 and led them from the Sky Bet Championship to a ninth-placed Premier League finish last season, with this term more than likely to end in a mid-table finish.
Next permanent Manchester Utd manager (odds via Sky Bet)
- Gareth Southgate - 2/1
- Graham Potter - 5/2
- Thomas Tuchel - 8/1
- Ruben Amorim, Roberto De Zerbi - 10/1
- Julen Lopetegui, Julian Nagelsmann - 12/1
- Thomas Frank - 16/1
- Simone Inzaghi - 20/1
- Jose Mourinho, Michael Carrick - 25/1
Should Erik ten Hag depart Old Trafford this summer, Sir Jim Ratcliffe's first choice to replace him is thought to remain Gareth Southgate, the current market leader.
Southgate, who is expected to end his eight-year spell as England manager after Euro 2024, was as long as 10/1 to become the next United boss prior to the latest speculation, with several firms cutting him into 2/1 favouritism.
England have reached a World Cup semi-final, European Championship final and World Cup quarter-final during the 53 year old's tenure.
Ten Hag's position has been under severe scrutiny this season, especially since the much-vaunted minority investment from Ratcliffe's Ineos group was confirmed.
They are undertaking a full-scale review of the club's football operations, which includes the managerial position.
United's dramatic victory over Liverpool in the quarter-finals of the FA Cup relieved some of the pressure but is unlikely to change the new minority owners' overall view.
