Chesterfield manager Danny Wilson cut a frustrated figure after seeing his side slump to a 1-0 defeat at home to Fleetwood.
Full-back Conor McLaughlin fired in an angled effort four minutes before the break just at the point the free-falling hosts had begun to build a head of steam.
Wilson said: "I don't know how we didn't get anything from that game. We didn't just deserve a point, we should have got all three.
"But we let in a sloppy goal and that was about the only thing we didn't do particularly well in the game."
Wilson, buoyed by Ched Evans' presence on the bench following injury and his court case, saw his side tumble to 22nd in the table.
He added: "That was difficult to take, I really feel for the lads, we dominated for large parts of the game, we had the odd counter attack against us but we didn't have the rub of the green."
Evans came off the bench on the hour mark and immediately lifted the crowd and forced a great save from sub keeper Alex Cairns, a former Chesterfield reserve.
Wilson said: "We knew he'd never do 90 minutes. Ideally I wouldn't have had to use him at all as we don't want him to break down again.
"It was bad luck or, from their viewpoint, good fortune when he saw a shot saved onto the bar."
Evans, who also picked up a booking for a foul, looks set to start at the weekend against leaders Scunthorpe after Wilson revealed fellow striker Conor Wilkinson would be missing for up to three months while Kristian Dennis sustained a calf injury during the game.
Cairns, 23, made his only previous league appearance five years ago for Leeds, also off the bench, in a 5-0 home defeat against Blackpool but he went on to make a number of fine saves to maintain his side's advantage.
Cod Army boss Uwe Rosler said: "We didn't start the game particularly well, we played too many back passes and square balls and invited pressure from them in the beginning.
"Then we adjusted and started to play the right way for an away side and the second half was much better and we should have killed the game off but we didn't and that made the last 10 minutes somewhat nerve-racking. The goal was very well taken by Conor."
