Spireites boss Dean Saunders is calling on his players to bounce back from Saturday’s meltdown when they face Colchester at the weekend.
Chesterfield looked to be cruising to three points as they led Wigan 2-0 with 10 minutes to go.
But Saunders’ men somehow managed to chuck away their commanding position and were eventually beaten 3-2.
Saunders said: “It’s a sickener when you are two up with ten minutes to play and looking comfortable.
“They had chances to score before their goal. They are a good team with dangerous players, the goal gives them a bit more hope and we could not make a mistake at 2-1, but we did.
“People start to take a step back instead of a step forward. The ball bounces the wrong way, it was gone now and we have to move on.
“We have gone on to lose it and that is football, it slaps you in the face when you think you are doing well.
“You see things like this happen often in football at the end of a game when you are 2-0 up and the game turns against you, we have just got to pick ourselves up now and move on.
“On another day we go away and win the game 3-0. We played against a good team and Wigan will beat most teams, they will be there at the end of the season.
“Whether you are a professional or playing on a Sunday morning, you always feel like everybody could have done something about it.
“I’m just ticked off that we had three points in the bag with 10 minutes to go and didn’t see it through.”
But, despite chucking the points away, Saunders said he could not fault his side’s performance.
“We were on the wrong end of a result, but I cannot complain about the performance. I thought we were excellent,” he said.
“Wigan are a good team and looked dangerous all afternoon, Tommy Lee has had to make a few saves.
“It was an open game and we played some good football, we were patient and got a great goal from Dan Gardner.
“They scored from a corner and that gave them hope and they threw everything forward. They have then got a penalty that was dubious, our lad says he got his foot on the ball.
“We had a few chances and it was a good performance.”
