9. Ricky Korboa
His first taste of professional football and there was plenty to be encouraged by. Took up good positions, linked play well and had a hand in the second and third goals. Just need to keep things simple at times... 8 Photo: Pete Norton
10. Matty Warburton
Town's injuries and lack of attacking signings presented him with a chance and he didn't disappoint. Worked extremely hard, fashioned a couple of half chances and got himself a richly deserved goal, very nicely taken... 8 Photo: Pete Norton
11. Harry Smith
He improved as the first-half wore on and took confidence from sticking away the spot-kick. Helped win it in the first place and then did splendidly to tee up Watson for Town's third. An encouraging display... 8 Photo: Pete Norton
12. Morgan Roberts
A lively cameo from the bench and his pressing helped Town keep up their intensity for the final 20 minutes... 6.5
