Spireites manager Dean Saunders felt his side fell short of their best after suffering a 1-0 away loss to Coventry City.In-form striker Adam Armstrong got the only goal of the game just after half time, the goal giving the hosts a lead they rarely looked like giving up.
After the match Saunders told PlayerHD what had gone wrong for his side: "We weren't as good as we normally are today, we gave the ball away too many times.
"They sat back and tried to counter attack us and if you give the ball away as much as we did in front of your own goal you are suspect to counter attacks.
"They could have scored more than they scored."
The Spireites made a host of changes for the match: Sam Hird, Sylvan Ebanks-Blake and Liam O'Neil returning from injury while Chris Herd made his debut at right-back.
"That's a new team again there today and you're going to expect teething problems," explained Saunders. "Chris Herd's come in and Liam O'Neil's playing in midfield so it's a different group of players and a few position changes.
"I can't expect everything to be perfect but we spent all week playing possession, keeping the ball and we gave it away too much today.
To compound the afternoon, substitute Mani Dieseruvwe received two yellow cards after coming on, initially for a tackle on halfway with second coming as the striker deliberately handballed as he tried to get on to the end of a cross.
"The first one's not a yellow card," said Saunders. "He's a bit unfortunate to get that but the second one's a definite yellow card, he's put his arms up.
"It was a great ball in from Gboly [Ariyibi] and he's inches away from getting the ball in the net and if he gets that we get a draw probably.
"I've said to him that he's got to think if he's already been booked. It's easy from the side but I can never understand why you'd make a daft challenge or do a daft thing like that."
