1. Bali Mumba - 7
Comfortable on the ball at right-back but was pinned back by Liverpool’s pressing play. Looks to be growing as a defender. Photo: Tom Banks
2. Owen Gamble - 7
Made some heroic blocks and tackles but managed to pick up a silly booking in the process. A Decent showing. Photo: Tom Banks
3. Adrias Edmundsson - 8
A colossus in the air and looks comfortable and strong on the ball. Photo: Tom Banks
4. Jack Connelly - 6
Hard for the midfielder to get on the ball, but held his shape well to provide Liverpool with a firm obstacle. Photo: Tom Banks
