John Sheridan says that he won't tinker much with his line-up for Tuesday night's game at Braintree Town.
The Spireites went down to a 1-0 defeat at Wrexham on Saturday and Sheridan has plenty of options at his disposal, but he has hinted that it will be largely the same team at Braintree.
He said: "I'm not someone who wants to rotate the team. I'd like to have a settled side and I'd like to keep us in the formation we're getting used to.
"I won't change too much. I don't think we're doing a lot wrong so I think I'd be daft if I made too many changes.
"I believe that in every game we've been involved in the game. I can't think of a team who's out-played us or deservedly beaten us.
"The only game I look at when we probably deserved to get beat was in the cup, against Brackley. Other than that, I think we've competed and been well in the game."
Sheridan expects Braintree to provide Chesterfield with a tough test. "They'll still believe there's enough points to go for to stay in the division," he said. "I'm not taking them lightly, whatsoever.
"It's a Tuesday night and I don't expect the pitch to be great. We've just got to carry on doing what we've been doing.
"It's probably the biggest game for me since I've been here. If we can win the game, it keeps us seven points clear of the bottom four so it's a big, big game for us."
Charlie Carter missed the Wrexham game and Sheridan explained that he was left out after suffering a hamstring strain. He added that the midfielder will be in his plans for Tuesday night's journey south.
