Skipper Robbie Weir insists the team are feeling good this week despite defeat last weekend and their current position in the table.
The Spireites suffered a 2-0 defeat last time out against Carlisle United, keeping Chesterfield in the relegation zone and fighting for their place in Sky Bet League Two.
However, Weir assures that the camp are in good spirits. "The gaffer has worked us hard as always but this week he's put it up a notch. The feeling is good - obviously we're in a bit of a difficult situation at the moment so it's good for the lads to get all amongst each other and know what's expected of each other tomorrow."
Weir meanwhile took time to speak about the formation of the team following the match with Carlisle, in which manager Jack Lester decided to operate with a diamond formation. "I think at the start of the season we played it really well, we got a couple of good results. We have different personnel this time and I don't think it quite worked at Carlisle, but we've got the players - we've got injuries coming back," Weir stated.
The Spireites have been missing experienced players at vital times this season but ahead of the Swindon game there could be returns for a few individuals who were previously missing through injury. "Experience is coming back and what a great time for them to come back," Weir said.
"We're in a bit of a difficult situation at the minute but we are still fighting to get out of it and we'll keep on fighting until the end," he added.
Injuries have meant that Weir has had to operate at full back. However, it's a role that he's familiar with from earlier in his career. The midfielder commented: "I played right back a few years ago when I was at Sunderland, so I have a rough idea of how to play there but it's a game of football.
"It's been a bit manic, I've been playing right back - I've been playing left back but you have to do the things you have to do for the team. It isn't a problem me doing that - I've quite enjoyed doing it," Weir reflected.
The 29-year-old has taken on a big role recently, having to deal with captaincy duties as well as playing out of position. "I treasure the moment of being captain at a club like this. It's an honour for me to do it. I've always wanted to be a captain," Weir expressed.
Going into this Saturday's clash with Swindon the Spireites are on a run of four defeats. Speaking about the run Weir noted: "As a group of players we see the position that we're in. It's not acceptable for us as players and as a football club.
"If we get relegated we're playing with our livelihood and pay bills. That's what the lads are getting in their head now. We don't want to get beat every week."
Weir meanwhile asserts that it doesn't matter how wins come - just as long as they start picking up results. "Anyone can beat anyone in this league - we've proved it at Luton, but we need to start worrying about ourselves. It's time to produce and start getting results, if that's pretty football or going direct and being dirty and scrappy, but at the end of the day if we're getting results that's the main thing," he revealed.
With the team on the run they're currently on, Weir has asked fans to stick with them as they aim to move up the table. "It's very frustrating for the fans. They're seeing their club bottom of the Football League - it's not great. They need to stay with us, they're our twelfth man," he explained.
"We will work hard, I know the gaffer and his management staff are going to get us out of this. Us as players we're going to give everything now until the end of the season," Weir concluded.
