Sam Hird insisted that his side will stay positive, while their League One future remains in their hands, following a disappointing 0-4 defeat against Oxford United.
The loss leaves Gary Caldwell’s men in desperate need of wins as the season reaches its tail end, but Hird asserted that the Spireites will keep fighting for survival.
“First and foremost it is just not good enough from every single one of us,” the centre-back admitted. “It is a disappointing result and it is not the result that we wanted.
“We know where we are in the league, we have known that for a good while now and we can only get wins to get out of the mess that we are in. Out there today we came nowhere close to where we want to be.”
Hird asserted that his side know exactly what is required of them in the remainder of the season, but struggled to explain what went wrong against Oxford, having started the game well.
“I think people look at things and question the shape or whatever, but there have been a couple of mistakes for the goals today. This has obviously changed the course of the game and given them the impetus to push on.
“Because of where we are in the league and with the players that we have got, when you go behind in games it can affect some people differently than others. But today, to a man, we weren't good enough.”
Chesterfield face two fixtures within seven days as they travel down south to Walsall on Tuesday and Swindon next Saturday, and the 29-year-old told Player HD that he believes his side can still get out of the relegation zone.
He said: “We said that the target from our next four games, starting with Millwall, was to get a minimum of seven points - and there is still a chance to get that - but it is going to be tough.
“It means beating both Walsall and Swindon, but while there is still a chance for us to stay in the league, we have to stay positive and we have got to be better than we were today.”
The Spireites have drawn their previous two matches on the road and Hird admitted that while these were good results, his side needs wins.
“They were okay results, if you look at the context of where we are in the league they are decent results, but we need wins, it is as simple as that.
“We need to go and win games, there is no point shutting up shop. That isn't how we play anyway, we don't play to shut up shop. We play to win games and that is maybe what leaves us a bit more exposed at the back. We have certainly got to be better than we were today.
