Spireites midfielder Sam Morsy gave his thoughts after his side played with ten men for 89 minutes and lost at home to Preston North End.Defender Sam Hird was adjudged to have pulled back Joe Garner in the second minute, and with the Lilywhites striker through on goal the foul led to a straight red card.
After the game Morsy expressed his upset at giving strong opposition such an early advantage.
"We're bitterly disappointed," said the midfielder. "You go into a game where your opponents are above you and you can't afford to give them a leg up, especially so early in the game.
"We had a couple of chances as well, big Byron up top's had a good chance and the goals will come for him.
"The disappointing thing is that we felt with 11 men today we definitely could have won this game. Even with ten men for spells we were the better team, so it was disappointing not to have the chance to give them a game today."
As well as controversy over the sending off Spireites players were upset with the build-up to the North End second goal, where 'keeper Tommy Lee appeared to be fouled, a view Morsy shared.
He said: "I've seen three lads go into Tommy, how the officials haven't given it I'll never know.
"We know we can't win every game, if they'd scored an early goal we still would have fancied ourselves to get back in the game but when you go down to ten men after two minutes against a decent side it's always going to be difficult."
However, Morsy reserved special praise for Preston striker Kevin Davies, making his first return to play at Chesterfield, where he started his long career.
"He's been an awesome professional," said Morsy. "You can see now that he looks after himself and he's a credit to himself and for me or any young player aspiring to get anything out of the game he's a great role model."
