Chesterfield manager Paul Cook and assistant Leam Richardson have put pen to paper on one-year extensions to their Proact Stadium contracts.
Their previous deals were due to expire next year but both have now been tied down to the club until the summer of 2017.
Cook joined the Spireites in October 2012 and brought in Richardson in the summer of 2013 as his deputy among widespread changes to the Spireites’ backroom team.
What followed was a blistering start to the League Two season which resulted in promotion to League One as champions and a Wembley final in the JP Trophy.
They have overseen Chesterfield’s rise in to the play-off picture this campaign, currently in fifth ahead of Saturday’s trip to Notts County.
And Cook is delighted to have secured 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,” said Cook.
“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.
“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 added: “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.”
