Spireites manager Jack Lester is looking forward to tomorrow's crunch trip to fellow strugglers Grimsby Town.
Lester insists that he, his staff and players are focused ahead the match against a Grimsby side who are just four points above Chesterfield.
"We're well prepared and looking forward to a good performance," said Lester. "We're aware of the importance of the game and it's one we're looking forward to.
"We've played in big games this season and they tend to bring the best out of the players so with that in mind, we're looking forward to a good performance."
With three games in hand on the Mariners, Lester is looking for consistency from his team as they bid to haul themselves clear of the relegation zone.
He said: "Inconsistency has been an issue and we're very aware that the performance at Port Vale wasn't what it was against Notts County.
"The energy and desire was there but technically we didn't look after the ball. We lost momentum in a game we were in control of.
"We've shown we can have individual games where there's only one winner, where we've played teams off the park. We should be able to repeat that, game after game."
The Spireites will be backed by a good following at Blundell Park - with over 1,300 tickets sold at the time of writing - and Lester acknowledges that the fans will have a part to play.
"The fact that we're taking so many will help," he said. "It'll give us that energy and that little boost."
Lester revealed that Ian Evatt has trained all week, but says that the experienced defender won't be available for the game. "He's definitely looser and has got a spring in his step, but he's not quite ready to play yet."
