Further signings are expected after Aiden O’Brien put pen to paper last week, with a host of players already linked with the Stadium of Light this summer.
So how could the Black Cats’ squad look on the opening day of the season if the rumours are true? Scroll down as we take a look:
9. AM: Lynden Gooch
At times last season, the American was unplayable and made himself an integral part of Sunderland's resurgence after the turn of the year. If he can sustain that form during this campaign, he'll certainly feature among the best players in League One. Photo: FRANK REID 2019
10. AM: Aiden O'Brien

11. ST: Danny Graham
A controversial link this summer has been that of former Sunderland striker Graham - who the Sun claim is on Parkinson's radar after leaving Blackburn. Could he be the man to fire Sunderland to promotion from League One? Photo: Charlotte Tattersall
12. SUB: Matija Sarkic
