The youth team defeated Barnsley 3-0 in a friendly match yesterday, thanks to goals from Robbie Foster, Levi Amantchi and Ify Ofoegbu.
Foster gave the Spireites the lead, when his effort from outside the penalty area trickled through the goalkeeper's legs and into the back of the net.
Amantchi doubled Town's advantage, rounding off a good passing move, when he tapped in Ricky German's cross at the far post.
Ofoegbu then completed the scoring, when he collected Amantchi's through ball, before firing across the goalkeeper into the bottom left-hand corner.
Miguel Llera's men are next in action on Saturday, when they travel to York City in the EFL Youth Alliance North East, 11am.
Chesterfield XI vs Barnsley: Jones, Hand, Sharman, Willock, Render, Ofoegbu (Sennett-Neilson 45'), Brownell (Howard 45'), Holmes, German (Rawson 45'), Amantchi, Foster (Walker 45').
