“As soon as the ball went into the net, I looked up and everyone in the stands was just going absolutely wild.
"It was totally crazy – I’ve never experienced a moment as electric as that."
“I have to give a big shout to Danny (Cowley), Zesh (Rehman) and all the coaching staff who gave me this opportunity.
“There was an earlier chance, but I had forget about the miss. It happens and I just needed to get myself into the box again.
“It was a great experience for me to play alongside so many good players and they help all of the academy boys.
“We’re young, but whenever we come in to train alongside them, they make us feel really welcome and comfortable.

“Hopefully there will be more opportunities in the competition this season so we can show what we can do.”
