Nigel Pearson
Pearson, like Allardyce, is also currently out of work, following his sacking as Leicester City manager at the end of last season.
Despite leading them to a brilliant survival in the final weeks of the 2014/15 term, the Foxes parted with the controversial character, with Sunderland a likely route back into club management.
Alongside Big Sam, the 52-year-old is a leading candidate for the job at Sunderland.
