The Spireites wrapped up an impressive 2-0 victory over Oxford City at the SMH Group Stadium, extending their lead at the top of the National League table to 23 points.
An early goal from Will Grigg and a second-half strike from Tom Naylor were enough to ensure the Spireites took away all three points.
Paul Cook named a completely unchanged line-up from the side that beat AFC Fylde 4-1 at the SMH Group Stadium.
The Spireites took the lead in the first minute. A corner from Liam Mandeville was whipped in from the right-hand side, Naylor flicked it on at the front post and Grigg was the first to react, knocking the ball away from close range.
Soon after the Spireites took the lead, with a shot from just inside the box, Naylor forced a great save from Tom Watson, who dived the wrong way but managed to deflect the ball away with his trailing foot.
The referee pointed to the spot when Harry Tyrer brought down an Oxford City player in the box.
Josh Parker stepped up to take the penalty. However, for the second game running, Tyrer guessed the right way and kept the penalty out, diving to his right.
Mandeville had a chance to double the Spireites’ lead, with an attempt from around six yards out, but Andre Burley dived in to make a fantastic block.
The Spireites went into the break with a 1-0 lead.
The Spireites doubled their lead in the 55th minute. Ollie Banks threaded a delicate ball through the Oxford defence, Naylor ran onto it and calmly slotted it past Watson.
Lewis Coyle forced a great save from Tyrer, tipping the ball over the bar from a quick shot on the turn from around the penalty spot.
Ash Palmer came close to making it two in two for the Spireites, but his side-footed effort bounced back off a post.
Moments after coming onto the pitch, Ryan Colclough almost made it three for the Spireites, driving into the box from the left-hand side, but his eventual effort hit a post and was gratefully collected by the keeper.
Parker had a chance to pull a goal back for Oxford in added time, but when he came up against Tyrer one-on-one, he curled his effort off-target.
After this impressive win, attention will now turn to Saturday’s away trip to Oldham Athletic.
