Tony Mowbray’s men also crashed out of the Carabao Cup in the first round after being beaten by Crewe Alexandra at home on penalties following a 1-1 draw on Wearside.
After Sunderland’s less-than-ideal start to the season, eyes have understandably towards transfers with sporting director Kristjaan Speakman and head of recruitment Stuart Harvey eyeing deals.
Here, we take a look at 12 active transfer and contract deals Sunderland are still working on this summer:
1. Amad Diallo
The Manchester United man ha picked up a slight injury during the Red Devils pre-season but it remains to be seen whether or not he will remain at Old Trafford this summer. Sunderland will be one of the interested parties with communication lines between the two clubs open. Amad, however, will have serious interest from other clubs. Photo: George Wood
