The 18-year-old striker - recalled from a loan at Northern League Division One side Belper - came off the bench to head home the goal which proved enough to knock out the holders Chesterfield.
"As a striker you obviously want to score, but to be honest it was my first game and I just wanted to get onto the pitch - the goal is a bonus," he told the club's official website.
"This week has been a bit weird really. I had been on loan at Belper and that came to an end on Monday. The gaffer told me that I would be involved in the game so I trained with the first team as I usually do during the week.
"I didn't really realise that I would be on the bench until about five minutes before kick-off. It took a while to sink in but the nerves didn't really kick in until I was stood on the touchline next to the gaffer ready to come on.
"I got amongst the goals at Belper and really enjoyed it but towards the end of my spell I didn't really play as much as I wanted to, lucky I could come back here and I got my chance - I really enjoyed it."
