The Cobblers, who agonisingly missed out on promotion to League One last season on the final day, are up there once again.
They have only won one of their last seven games but they have the division’s top scorer in Sam Hoskins, who has 12 goals in 13 appearances.
Chesterfield go into this one on the back of a five-game unbeaten run, including three successive wins at home.
Let’s take a look at how the Spireites could line-up for this one...
9. Tom Whelan - CM

10. Armando Dobra - LW
Might not play all of the game with one eye on Wealdstone but he might get 60-70 minutes. It will be interesting to see what problems can he can cause against 'better' players. Photo: Tina Jenner
11. Kabongo Tshimanga - FW
I think Joe Quigley will be the preferred option for Wealdstone away and he has only just come back from a hamstring injury so it makes sense to start Tshimanga. He will be desperate to show what he can do against a Football League side. Photo: Lewis Storey
