5. Dennis Cirkin - 6
As you’d expect, defensively robust and drove forward where he could. 6 Photo: JPI Media
6. Luke O'Nien - 5
Did well, but saw yellow for an absolutely crunching challenge on Shomurodov. After an aerial challenge with Ibanez shortly after, Mourinho was on the pitch and the ref had a quiet word to see him subbed off. Otherwise steady. 5 Photo: JPI Media
7. Jay Matete - 6
Excellent through the first half an hour, making interceptions and causing problems. Definitely tired through the second half as Roma poured forward on the counter but it’ll be 90 very valuable minutes for him. 6 Photo: JPI Media
8. Elliot Embleton - 7
Looked really useful, dribbling away from his marker on a few occasions. No killer pass, but there wasn’t much movement in front of him without Stewart. 7 Photo: JPI Media
