After the Spireites picked up another win in the 3-2 Proact match with Bristol Rovers, Danny Wilson spoke about the difference his side have now found.
Ian Evatt levelled for the Spireites after Peter Hartley had given Rovers the lead early on. Two Jay O'Shea strikes saw the Spireites clear, before Billy Bodin set up a tense finale with a visiting second.
Wilson pointed to the clinical nature of his side's finishing in the match as well the Spireites' ability to see the game out with the Pirates pushing for a late leveller.
"It's been a fantastic return in the last two games," said the manager. "I think the lads have really deserved what they've come back with. Today, being a goal down showed the character as happened in midweek.
"There's a lot of fight in the dog yet, and that gives us great confidence. It was a tough game again today and you can see why Bristol have done so well; they're strong, they're experienced, they know the game and have some good pace.
"For a large part of the game we did well. In the back-end of the game they chased the game and it was all hands to the deck. We did well and managed the game at times - we took the ball to the corners and that's what you've got to do.
"What we are doing is seeing out games better and seeing them out better than we were at the beginning of the season, that's why we've been able to gain six points in the last two games."
Next up for the Spireites are Wycombe Wanderers in the FA Cup, and the Chesterfield manager is hoping to translate the recent league spurt into an extended Cup run.
"We're still in the Cup so we're delighted that we've got a game next week, "he said. "With the form that we've shown in the last five or six games, let's hope we can take that into the game and progress."
