Goalkeeper Tommy Lee has signed a new contract to keep him at the Proact Stadium until 2016.
Lee's previous deal was due to expire at the end of the season but he delighted both the club and it's supporters alike by putting pen-to-paper on the three-and-a-half-year deal.
Amidst speculation around his future, the 27-year-old sighted the ambition shown by the club and new manager Paul Cook as a major factor in his decision.
Speaking to Spireites Player, he said: "It's something that we've [Tommy and the club] been talking about for a few weeks now and we came to an agreement in the last week or so and I'm pleased to sign.
"I think with the new manager coming in, you can feel the ambition people have got around the place, not just on the playing staff but in the boardroom as well.
"There's a lot of ambition at the club and everything's in place for us to move forward and get up that pyramid.
"Hopefully, with the players that are at the club at the minute and the players that may be coming in in the future, it looks like it's got a bright future and I am pleased to be a part of that."
The three time Supporters Player of the Year endured a frustrating start to the campaign, missing a number of games through injury.
With that behind him now, Lee wants to see the Spireites push on into the promotion picture during the second half of the season.
"That's got to be the aim for us this season. We've got to get focussed on getting as many points as we can, hopefully we'll be pushing the play-offs and the automatic spots," Tommy said on his ambitions for the season.
"It's a tight league, three wins on the bounce, four wins on the bounce can put you right back up in the mix and that's what we're looking to do in the next couple of weeks."
