A strike early in the second half consigned the Black Cats to defeat, despite creating a number of good opportunities against their top flight opposition. But who shone and struggled in the game? Scroll down to see how our Sunderland AFC writer Phil Smith rated each individual performance – with some positives to take across the board:
9. Will Grigg - 6
Frustrating second half but looked bright in the first. Battled well, showed some good touches and almost scored an early goal. 6 Photo: Ian Horrocks
10. Charlie Wyke - 5
Quiet as Belenenses comfortably saw out the closing stages. 5 Photo: FRANK REID
11. Alim Ozturk - 6
Looked tidy enough, but in truth was rarely tested in a sedate end to the game. 6 Photo: Ian Horrocks
12. Max Power - 6
Frustrated by the referee, who penalised him for a few marginal challenges. But an exceptional effort to be back on the pitch so far ahead of his schedule and testament to his conditioning. A big boost for Jack Ross. 6 Photo: Ian Horrocks
