Spireites assistant manager Brian Carey saw his squad in action for the first time at Matlock Town on Thursday night, with the Spireites opening their pre-season with a comfortable 3-0 win.
Jay O'Shea converted from the penalty spot 14 minutes in after Sylvan Ebanks-Blake was fouled by the Matlock 'keeper, and four minutes later Ebanks-Blake himself doubled the lead with a steady header.
Manager Dean Saunders made 11 changes at half time and one of the new men, Armand Gnanduillet, capped a promising display when he rifled home a third late on.
After the match Carey was pleased with the performance and the chance to see all of the large playing squad that were brought to the Autoworld Arena for the match.
"We managed to get everyone who came here on the pitch, all 25 players who came here with us including some triallists," he said. "It's just nice to see everyone get a game, we've seen them all in training but it's good to get them on the pitch with no injuries.
After impressing for 38 minutes, Ebanks-Blake was removed from the action in the first half, but Carey was quick to dismiss any injury concerns for the new Spireites striker.
He said: "It wasn't necessarily that everyone was going to get 45 minutes. Sylvan got just over 30 minutes and that was fine. We had other players who can play there and there's always the risk of injuries - but today was fine, no injuries.
"The secret for him is just to keep himself fit and we think he can do that. That's why we got him here because he's scored goals regularly in the Championship and he's proven tonight what he's about."
Chesterfield started proceedings with a 4-4-2 formation which after the break reverted to closer to a 4-5-1 with the altered playing staff, though the assistant manager suggested that there was little to read in the set-ups looking ahead.
Carey said: "The 4-4-2 formation we started off with really wasn't set in stone because Sam [Clucas] really had a free role and combined well with Sylvan [Ebanks-Blake].
"Right now it's not about formations, it's just about the lads getting through and the lads getting ready for the start of the season."
