A solid night at the base of Wednesday's midfield. Managed to contribute further forward on occasion too. Photo: Steve Ellis
Brilliant to watch. Akin to a cheat code at this level. Scored two excellent goals and grabbed an assist but seemed to pop up everywhere in Burton's half. Could have had a hat-trick. So, so good. Photo: Steve Ellis
Three in three for the big man, who converted from close range when the ball was at an awkward height. Have seen them blazed over. Thankfully they tend to go in when you're among the goals. Photo: Steve Ellis
One or two dangerous moments in the first half and showed some nice touches leading the line alongside Paterson. Replaced on the hour mark. Photo: Steve Ellis
