Combative defender Pearce was the overwhelming winner of the prestigious Daily Echo-Micky Cave fans' award 12 months ago.

"It's been a real team effort and it is great that so many players could win it. It shows we've all stuck together and that everyone has performed well. Everyone has played a part."
