Ahead of the new season, Sean O'Callaghan has been brought to the club as the Spireites' dedicated performance analysis.With analysis becoming an ever-more relied upon tool for clubs to assess their squad members as well as to scout opposition, O'Callaghan has been briefed to head up analysis of the first team.
"The game's changing all the time," said the 26-year-old on the changing face of football. "It's become more sports science based, so it takes a lot of work with the video; you're filming training, you're filming games, re-going over all that.
"Then, looking at when the season starts you're looking at the opposition and the way they play, the trends you can spot and which set pieces they do.
"You're giving the manager and the coaches as much information as you can give them to help them prepare the boys for the game."
O'Callaghan joins the Spireites from across the divide at Mansfield Town, where his work was highly-praised by Stags manager Adam Murray.
"It was a good season," said O'Callaghan of his time at Field Mill. "The aim was promotion and the club just fell short of that. I was given the opportunity to head up their first team analysis and I believe a successful analysis department was built.
"I did get a lot of praise, and I'm looking to do the same thing here now. We had success with penalty saves, little things like that which win you the three points on a Saturday."
Joining the Proact staff ahead of pre-season and part of the traveling group in Hungary, O'Callaghan is pleased with the welcome he's received at the club and is impressed with what he's seen of the squad so far.
"They're a good bunch of lads; the gaffer, Morgs, they've all been brilliant, all the staff have welcomed me.
"You can see from the hard work that's gone in over here, it's hot, humid and the boys have stuck to it, dug deep and that's what you want to see come the first game of the season when it really matters."
