31. Bobby Duncan (Fiorentina)
This one came from left-field. The Sun claim that Duncan, formerly of Liverpool, is being eyed by the Black Cats for a loan move with a view to a permanent switch. Photo: Emilio Andreoli
32. Declan John (Swansea City)
Phil Parkinson confirmed that the full-back is one of the options being pursued by the Black Cats as they look for cover for Denver Hume. He's understood to be available on loan this month having found opportunities limited at Swansea. Photo: Alex Livesey
