Derbyshire, who was a community coach at Blackburn before turning pro and had started taking his badges, is one of the best qualified young players around.
"I always wanted to be a coach," he said. "I did my Junior Managers and was onto my final assessment with the FA but got taken on at Blackburn at that point.
"To be honest, it's a great job, you have a football at your feet every day and can influence the development of other young players.
"That was the line I wanted to go down - I also wanted to play at the highest level possible, never thinking I'd make it this far."
