Chesterfield right-back Drew Talbot admitted Saturday's performance against local rivals Rotherham wasn't good enough, but failed to declare the Spireites' promotion hopes as over.
Paul Cook's side suffered a narrow 1-0 defeat against the Millers in front of a packed house at New York Stadium on Saturday afternoon, although in truth it could have been more as the home side dominated the game for the majority of the contest.
The defeat was Town's fourth in just seven games since the turn of the year and Talbot was left perplexed at his side's recent form.
"There's no explanation," he told Spireites Player after the game.
"If you can't get up for a game when there's 11,000 fans here then there's something seriously wrong.
"We were just flat today. They gave us a torrid time in the first-half. We thought we'd weathered the storm quite well, even though they'd had a couple of chances we were still in it.
"The plan was to come out and try and create a little bit more in the second-half and that never really materialised."
Former Manchester United striker Daniel Nardiello and strike-partner Alex Revell were of constant torment to the visitors' back-four, with the former stumping the foot of the post inside three minutes as Steve Evans' side signalled their intent early on.
Neither side created much in the way of a clear cut opening until after the break, when Revell somehow fired wide after racing clear of Neal Trotman.
Nardiello then blazed a free header over, but captain Johnny Mullins made no mistake when he powered home a 58th minute bullet past the helpless Tommy Lee to ensure the points stayed in Yorkshire.
Sam Togwell almost restored parity immediately after when he drilled into the stanchion from the edge of the box and the industrious midfielder saw a late equaliser chalked off for an alleged offside against second-half substitute Armand Gnanduillet.
Both Talbot and the Ivorian striker missed close range headers in stoppage time, but they couldn't rescue what would have been a flattering point.
"They had chances but you're always going to come under pressure against a team like Rotherham, they are a decent team.
"We thought we weathered that quite well. Even though we did have problems, we were getting in behind a little bit and we addressed that at half-time.
"We believed we were still in it and sadly they nicked the goal and it took them to score the goal for us to kick on. It's not good enough.
"It's going to have to be addressed, we can't keep letting that happen. We should be coming here and looking to win and to be honest today, it never really looked like that.
"You can't leave it until there's 20 minutes to play. We dug in, we never gave up and could have even won it with a couple of good chances at the end."
League Two leaders Gillingham are the next visitors to Whittington Moor and the sides shared a 1-1 draw when Tommy Wright took his side to Priestfield back in September.
The defeat in Yorkshire saw Town slip eight points adrift of the League Two play-off places, but with 42 points still to play for Talbot believes a top seven place is still in their sights.
"Regardless of who we play now, we are going to have to win," he added.
"We're going to have to go on a good run to claw our way back but we're capable of that, we believe that in there.
"We're going to have to knuckle down ever harder. It'll be a good game, they are going to come and believe they can win so hopefully we can stamp our authority on the game, get three points and make up for today."
