Leam Richardson said he and Paul Cook will be treating the visit of former club Accrington Stanley as just another game in League Two.
The Chesterfield assistant manager played over 100 games during eight years at the Crown Ground which included two spells in the managerial hot seat.
The Spireites are riding high at the top of the division while Saturday’s visitors to the Proact Stadium are rooted to the bottom with just a point to their name.
Richardson said they won’t underestimate Accrington, who are managed by former Premier League striker James Beattie, and admitted there is an ‘extra bit of spice’ to the encounter.
He said: “It’s just another game in respect of we want to win. It’ll be a tough game, Accrington have come up against some good tests so far this year.
“They’ve played some good football, I’ve seen them a couple of times, and their performances are not reflected in the results.
“They’ve just not had the rub of the green but I’m sure they’ll be a good test for us.”
Three points against his former club on Saturday will make it Chesterfield’s best ever start to a league campaign.
Richardson added: “No team in League Two is a walkover. They certainly will not come here and lie down, they’ll give us everything they’ve got with both barrels and we’ll have to make sure we meet it head on.”
Nathan Smith is in a race to be fit for the game with an ankle knock while Matty Brown is out with a hamstring injury.
Club captain Ian Evatt is in contention for his first appearance since returning to the club in the summer after his return to full fitness.
