Former Blues skipper Tom Naylor settled matters with a first-half header which deservedly gave Paul Cook’s impressive non-leaguers victory.
It was a season’s worst display from John Mousinho’s men, particularly in the first half, and here are our Pompey player ratings...
17. Abu Kamara - 3
(Replaced Jack Sparkes on 60 mins) Dreadful upon his introduction, failing to get past the right-back and too often making the wrong decision. Eventually switched to the right and did little better. Comfortably worst performance of an encouraging time at Pompey. Photo: Jason Brown
18. Kusini Yengi - 5
(Replaced Terry Devlin on 60 mins) Gave Pompey a bit of height and muscle, but even that wasn't enough to find a way through Chesterfield's defence. At least he put himself about a bit, unlike others. Photo: Jason Brown
