At the time of writing, the Spireites don’t know if it will be Woking or Bromley that they will face at the Technique Stadium.
But what we do know is the winner will go to Wembley and be one more victory away from promotion.
There’s a couple of selection decisions for manager Paul Cook to ponder, so let take a look’s at how they could line-up...
5. Bailey Clements - LB
Recalled to the side in place of Maguire against Maidstone and capped a good performance with a goal. Does he keep his place? You'd have to think he will. Photo: Tina Jenner
6. Mike Jones - CM
Got a solid 75 minutes under his belt against the Stones after being given a breather in the last couple of games. Whether it is Woking or Bromley, they will be physical and probably play on the counter, so having Jones as the 'sitter' will be vital. Photo: Tina Jenner
7. Ollie Banks - CM
He was not risked against Maidstone because his knee flared up during the week. Danny Webb said it was a not a bad one and that he would 100 per cent be available for Sunday. Oldaker had a good game on Saturday so does he keep his place or does Banks come back in if fully fit? The physicality and height of the opposition makes me sway more towards Banks.
