Spireites midfielder Jak McCourt admitted that Town weren't at their best as they slipped to a 1-0 defeat at Wycombe Wanderers yesterday afternoon.
A single goal from Luke O'Nien was enough to settle the points in a game where both sides failed to create many openings.
Reflecting on the game, McCourt said: "It wasn't the best performance from the lads today.
"We dug deep and we tried to get the goal back. I thought we deserved at least a point today but the performances we've done in the last seven games - it just wasn't the same today.”
The team were on a run of six matches without defeat in the league, a succession of games that has seen them rise off the bottom of Sky Bet League Two. However, after an unfortunate defeat on Saturday, McCourt stated: "We're devastated that it's come to an end."
Every team is now well into the busy festive period, but Jack Lester's team will be doing so with what is now an extremely stretched squad. "We've got a few injuries, but that doesn't justify coming here and losing," McCourt added.
Despite injuries, the midfielder insists that the players will travel to Stevenage next Saturday with the desire to make up for this defeat.
"We just need to make sure next week against Stevenage that we go there and we pick the three points up.
"We'll work really hard in training and put things right and go there and get the three points," McCourt asserted.
Although the Spireites unbeaten run has come to a close, there are still plenty of positives to take from what has been a resurging period for the club.
One of the encouraging signs is being able to compete with some of the best teams in the league.
"People have said we're competing against teams going for promotion but that should be us and that's a given from the lads in the dressing room,” the former Northampton Town man added.
"You'll get that every week but it was a disappointing result today and hopefully we can put that right next week.”
Another pleasing aspect has been McCourt's midfield partnership with Louis Reed and Robbie Weir in recent weeks. "That was the game plan today - to get us three on the ball - and I thought Wycombe dealt with that really well to be honest. They stuck a man on us each," he analysed.
"At times we're cutting through teams easily and we're getting in there. We just need to try and put those chances away. Playing in there with Reedy and Robbie is good and hopefully that continues.”
