The 60-year-old took the job at the Stadium of Light last season after Alex Neil's departure to Stoke City and led the team to a play-off semi-final.
However, Mowbray has now been dismissed with Sunderland sitting ninth in the Championship on 27 points, three away from the top-six spots.
The Black Cats are next in Championship action against West Brom at the Stadium of Light on Saturday after their recent 1-1 draw with Millwall at The Den.
Here, though, we take a look at the field of candidates to replace Mowbray at the Academy of Light and who the clear favourites are:
