Assistant manager Tommy Wright hopes Chesterfield do not buckle under the pressure of the occasion when they host bottom-of-the-table Rochdale.
The losers at the B2net Stadium on Saturday will be relegated from League One.
The Spireites face a third straight game knowing that anything but a victory will see them go down. However, a win may also not be enough to prevent an immediate return to League Two if results elsewhere go against them.
Ahead of the game, Wright told the club's official website: "We go into it buoyed by back-to-back wins. I thought our performance in the last home game against Wycombe was particularly good, while at Hartlepool last week we came from behind to win for probably the first time this season.
"But the pressure was off in those games as it seemed we would be on our way down. We will be under pressure on Saturday now because we have given ourselves a chance. It is up to whatever team we select now to handle that pressure and produce another good performance.
"We will get our own house in order first and take care of our own result, and then hopefully worry about what has happened elsewhere."
