Another midfield option could be Barnsley's Mowatt, who is out of contract in the summer - although the Tykes do have an option to extend his deal. Photo: Lewis Storey
10. Morgan Fox
A target for Sunderland last summer, Fox is out of contract in June and could provide a new left-back option. Sheffield Wednesday, however, are keen to tie down the former Charlton Athletic man to a new deal. Photo: James Chance
11. Craig Forsyth

12. Joel Coleman
If Sunderland require a new option between the sticks in the summer, they could do far worse than Coleman - who faces an uncertain future at Huddersfield Town. Photo: Nathan Stirk
