10. Danny Rose
Integral to all that was good about Town's play. Great work to win the penalty before he was in the right place to make it two. Could have finished with a hat-trick on a tireless and productive evening... 8 CHRON STAR MAN Photo: Pete Norton

12. Caleb Chukwuemeka
Gave the team something to hit up front although couldn't make the ball stick as often as he would have wanted... 6
