A quieter night than that of some of his team-mates. His effort to stop Burton's equaliser looked a little half-hearted but atoned by assisting Bannan's second goal. Photo: Steve Ellis
A superb night for Marvellous Marvin. Deployed high up the pitch to good effect. Produced numerous dangerous deliveries, including a wonderful low cross for the opening goal. Scored the second best goal of the night with a half-volley from the edge of the box. Photo: Steve Ellis
