1. GK: Thorben Hoffmann
Had a mixed debut against Accrington Stanley but showed his ability with the ball at his feet. Looked a little hesitant from crosses and didn’t have many shots to save. Will be expected to keep his place. Photo: JPI Media
2. RB: Carl Winchester
Scored his second goal of the season against Stanley and continues to impress at right-back. Photo: JPI Media
3. CB: Bailey Wright
Expected to replace the suspended Flanagan in defence. Wright has impressed with some late cameos this season and his experience will be valuable alongside teenager Callum Doyle. Photo: JPI Media
4. CB: Callum Doyle
Had a few nervy moments against Stanley but came through a tough battle well and showed his class on the ball. Photo: JPI Media
