6. Sunderland v Doncaster (h) January 25
Doncaster look like they could be a real threat to the division after finishing in the play-off places last season. A good result against Rovers at home could be pivotal. Photo: Stephen Pond
7. Sunderland v Portsmouth (a) February 1
The middle fixture in a busy three-games-in-10-days spell, Sunderland proved they could do a job at Fratton Park in the play-offs last season. Taking points of League One rivals would massively aid Sunderland’s credentials. Photo: Pete Norton
8. Sunderland v Ipswich (h) February 8
Coming down from the Championship, Ipswich have been tipped as pre-season favourites to win League One outright. A stern test of Jack Ross promotion credentials. Photo: Stephen Pond
