Spireites player of the year Sam Morsy has signed a new deal to keep him at the Proact until 2016.
The 22-year-old, who joined from Port Vale last summer, previously had a year left on his contract.
Morsy said: “We had a great season collectively and individually I thought I did well so I’m delighted to have signed my contract. The manager showed belief in me, making me a mainstay in midfield and I knew exactly what he wanted me to do.
“When a manager believes in you that much, it is easy to repay. The fans also warmed to me straight away, which was a massive help.
“We want a successful season in League One we’ve got a very strong spine to the team, with a mixture of youth and experience and strengthening the squad will give us a very good chance next season.
“You saw what Rotherham have done and if we strengthen I don’t see why we can’t have a successful season.”
It’s expected that fellow midfielder Dan Gardner will be next to commit himself to the club for a longer term.
It’s a somewhat low-key start to the new season for Paul Cook’s Spireites with none of the division’s heavyweights due to be played in August.
Whilst opening day hosts Leyton Orient may have been the beaten play-off finalists last season, they’re not among the favourites for promotion.
Not until mid-September, when Spireites make a Tuesday night trip to Preston, do they face a team tipped for a top six finish, though that’s rapidly followed by three of the next four matches being against teams tipped for upper echelons; Doncaster Rovers, Blades and Bristol City.
The season swan-song, at Bramall Lane, is sure to be a real humdinger.
