Chesterfield went down to a 2-1 defeat at Colchester United and manager Paul Cook spoke to Spireites Player after the match.
Sam Clucas had given the Spireites a first minute lead, but second half strikes from Rhys Healey and Freddie Sears saw the game swing in United's favour.
In the wild and windy conditions down in Essex, Cook felt something was missing from his side.
He said: "We're all very disappointed. It was a tough night for football, I thought first half we worked hard at being hard to break down. You just sense that there's something not right and it keeps coming out.
"We've just had a good chat in there with the players and it's down to us to work harder as a group and as a club to come through it.
"It's all about players. Players are what make you look good and you must stand by them when it hasn't gone well. I've sensed for a bit that we're just not right and I think tonight's performance has re-iterated what I've been seeing.
Aside from the early goal, the visitors had periods where they were on top, but were unable to grab a second goal.
Cook said: "There have been a few good spells in all the games we've played and that's what separates teams.
"Today we've played against a very good Colchester team- a very honest team with great rotation and great movement. Today they scored two great goals and you've got to give them credit for winning the game.
"We'll be back in tomorrow and we'll look at ourselves."
The Spireites have been involved in a number of entertaining matches this season at remain in the top half of the table, but Cook feels there is plenty of room for improvement.
He said: "The balance of our team isn't right, out of possession it's not right and defensively we're not strong.
"We look like we've got a goal or two in us but we also look like we're going to concede and it's something we're going to look at and try to address."
Cook also applauded the hardy 252 Chesterfield fans who travelled down for the match at the Weston homes Community Stadium.
He said: "We thank the supporters for travelling down in great numbers on a Tuesday night."
