New signing Richard Brindley points to mental strength as the reason behind getting back into league football.
The young full back was released by Norwich City in the summer and dropped down to BlueSq South with Chelmsford City in order to play first team football.
Speaking to Spireites Player, he said: "Basically I just said to myself that I need to play first team football and there were teams that were interested - pro clubs, reserve team wise.
"But for me I thought I was ready to play at a higher level and I wanted to play with mature, experienced players so I took a step backwards and pushed to take a step forward.
"My agency said to me, obviously you are better than this and you know you can push further. I trusted him, pushed hard and Chesterfield gave me the opportunity."
But Brindley did state that he found it tough after being released by the Canaries.
"I found it hard taking a step back because a lot of people in the league and out of the league were telling me it's hard to get back into league football," Richard said on how tough it was for him after leaving the Premier League side.
"A lot of people that get released end up being stuck here [in non-league football] and obviously having the doubts in your mind, whether you'll get the cjance or not, does play on your mind but I just kept pushing, had faith in myself and it paid off."
An attacking right back, Richard is keen to grasp the opportunity given to him by the Spireites.
"He [Paul Cook] just said that you're a good player and I deserve a chance and I'm grateful that he has given me the opportunity to show people what I can do and what I have wanted to do for a long time, just have a chance to progress."
