Neil Warnock is the latest manager to express interest in the vacant Sunderland head coach post.
Sunderland are searching for a replacement for Lee Johnson after he was sacked on Sunday evening in the wake of the Black Cats' 6-0 defeat at Bolton 24 hours earlier.
Much-travelled Warnock is out of work after leaving Middlesbrough in November and is understood to have contacted Sunderland about the role, potentially with a view to taking charge initially until the end of the season.
