The Black Cats have parted company with Parkinson after a disappointing run of form, meaning the club are now searching for the third manager of the Stewart Donald regime.
So who is available, who could come under consideration and what names would fans like to see given a shot? We round-up the early runners and riders for the Stadium of Light vacancy:
9. Daniel Stendel

10. Sam Allardyce
Another name that would undoubtedly please supporters and will be touted in some quarters - but Allardyce is unlikely to drop into the third tier. Photo: Ian MacNicol
11. Sol Campbell
