The youth team continued their extraordinary winning run with a 3-0 victory over Notts County in a bad-tempered league game at Langer Lane.
Lewis Sugden scored a first-half free kick to give the Spireites the lead, with the set piece award also seeing the Magpies reduced to ten men for denying a goalscoring opportunity.
Striker Jake Beesley ensured Chesterfield would stay on top of the table with a brace to confirm the points.
Youth team coach Mark Smith was pleased to get the victory, though felt his team were far from firing on all cylinders.
"It was another win and I while I didn't think we were at our best we've now got into the habit of winning games even when we're not at 100%.
"Notts County were decent, they had some good players. They had a striker who could have been a handful, but we tried to keep him in, for us, good areas of the pitch - up near the half way line."
The match was marred by ugly scenes at the interval, and Smith spoke of the events and those surrounding the first half dismissal.
"They had a man sent off after half an hour, rightly so in my opinion. George Milner nicked the ball off the defender and was clean through and was brought down on the edge of the box.
"It might have been in the box, so maybe we should have had a penalty, but actually Lewis Sugden scored from the resulting free kick so that helped us off on our way.
"There was a bit of a brawl at half time, which I though took the gloss off the second half. But we managed to get two more goals and keep a clean sheet, so that was pleasing."
