A fine first-half strike from Max Power proved enough for the Black Cats, who sealed their passage to the fourth round of the Carabao Cup at Bramall Lane. But which players came away with extra credit from South Yorkshire, and who has room to improve? Scroll down and click through the pages to see who our Sunderland AFC writer, Phil Smith, rated highly after the shock triumph:
5. Laurens De Bock
Got away with a couple of uncertain moments with his positioning early on and just grew and grew into the game. Defended very well and read the game superbly from a defensive perspective. 8 Photo: FRANK REID
6. Max Power
An outstanding strike to give his side a lead that they protected with great desire. Snapped around misfield and covered a huge amount of distance. 8 Photo: FRANK REID 2019
7. Dylan McGeouch
So tidy at the base of midfield. Swept up danger, moved the ball efficiently. 7 Photo: FRANK REID
8. Luke O'Nien
His best performance in the advanced midfield role. Perhaps benefited from not being required to be too creative on the ball but ran himself into the ground, pressed well and was a constant outlet for his teammates. 7 Photo: FRANK REID
