Chesterfield have handed boss Paul Cook and assistant Leam Richardson one-year extensions to their contracts at the Proact.
The pair are now tied to the club until the summer of 2017.
Cook’s time with the club has been a major success with the League Two title and a strong push for promotion from League One this term.
And he is delighted to secure his future.
“Along with the rest of the coaching staff, I was brought in to do a job and in football it’s always a difficult job in an ever-changing world,” Cook told the club’s official website.
“I’ve been here now for two years and four months and I think I’m in the top 20 longest-serving managers, which is quite amazing.
“I’d just like to thank the chairman, Chris [Turner], the board of directors and all the supporters for all the faith they’ve shown in me.”
“We feel we have a very strong unity here together as a club,” Cook added.
“Any manager will be clamouring for time, but in football today we don’t get that.
“The club is very important to us all. Loyalty in football now is a very hard thing to come across and as a manager or a player I think you need to show that.”
Chief executive Chris Turner says the club are keen to maintain their progress and see Cook as the man to lead the efforts.
Turner said: “It’s important that we keep this project going forwards. After the developments of the transfer window, where we brought in five new players and Eoin [Doyle] left the club, we’re showing that everything’s positive at the club.
“In the two and a half years that Paul’s been here, the progress has been there for all to see. Out on the field of play we’re fifth in League One, challenging for a play-off spot and we’ve just sold our first million pound Chesterfield player.
“For the first time in a long time there’s a very positive and bright looking future in front of us.”
