Chukwuemeka is hoping last season's injury woes are behind him.
"I pushed myself hard," he told the club's website. "I had multiple training camps to ensure I returned fit and strong. That I think showed against Wrexham. I still felt it a little toward the end of the game, but the work I'd done meant I was in shape to play the full 90."
Chukwuemeka also said, "Of course, it was frustrating.
"I had waited a long time for my chance and I had just got into the team. But things happen for a reason and I still took purpose from last season because there are positives you can take from a negative.
"Physically and mentally I developed – and I always looked to the future rather than focus on my present struggles. I kept on praying and I think my relationship with God is one of the reasons I stayed grounded and mentally strong.
"My family was also with me every step of the way to help me in the areas that I couldn't do by myself."
