The transfer window has closed – with Sunderland boss Michael Beale preparing his squad for Sunday’s big Championship match against Middlesbrough.
In total, the Black Cats made three new signings during the recent window, while some players were allowed to leave the club permanently or on loan. Several players remain sidelined with injuries ahead of the Middlesbrough match, including Patrick Roberts, Dennis Cirkin, Aji Alese, Niall Huggins and Bradley Dack.
Here’s what Sunderland’s starting XI and bench could look like, only including the players who are currently available:

17. SUB: Callum Styles
The 23-year-old will add competition in Sunderland's midfield after joining the club from Barnsley. Styles has signed for the Black Cats an initial loan deal, with a club option to make the deal permanent at the end of the season. He has also played as a left-back earlier in his career.

19. SUB: Mason Burstow
The Chelsea loanee has said he never thought about returning to his parent club in January, despite his lack of senior game time. Burstow scored his first Sunderland goals against Stoke last time out and will hope it’s the first of many. Photo: Frank Reid

20. SUB: Hemir
Sunderland opted not to send the Portuguese striker out on loan. The 20-year-old has returned to the Black Cats' matchday squad for their last three league games. Photo: Frank Reid
