The Black Cats claimed an important win over Birmingham before the World Cup break and now have several first-team players back from injury.
Lynden Gooch, Aji Alese and Dennis Cirkin all missed the match at St Andrew’s but are available again
Striker Ross Stewart has also been training with the team and could be in the sqaud to face Millwall.
Here’s our predicted line-up for the match:
9. CAM: Adil Aouchiche

10. LW: Jack Clarke

11. ST: Mason Burstow
With Nazariy Rusyn an injury doubt and Sunderland still monitoring Eliezer Mayenda’s return, Burstow could receive another opportunity up front. Photo: Frank Reid
