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:
1. GK: Lee Burge
Having spent most of last season as understudy to Jon McLaughlin, Burge is set to be the Black Cats' number one at the start of the term - even though Phil Parkinson is eyeing another stopper. Photo: FRANK REID
2. CB: Jordan Willis
Arguably Sunderland's player of the season last term, Willis is sure to be a key part of the squad moving into the new campaign. Photo: Frank Reid
3. CB: Bailey Wright
The Australian was a key target for Parkinson this summer after his impressive loan spell at the Stadium of Light - and will form a key part of the back three moving forward. Photo: Frank Reid
4. CB: Charlie Goode
The Northampton Town skipper has been linked with the Stadium of Light, but is also thought to be attracting interest from the Championship - with a £750,000 asking price slapped on his head. Photo: David Rogers
