League-leading Swindon Town brought the Spireites' unbeaten start to the year to an end with a 3-1 home win at the County Ground in a well-fought contest.Chesterfield went to Wiltshire to attack and after Jack Stephens had put the hosts ahead, Sam Clucas continued his goal-scoring week with a smart leveller.
However, Swindon soon struck back through John Swift before Andy Williams sealed the win moments after half time.
After the game, Spireites boss Paul Cook prasied the afternoon's opponents but felt his side's defending had assisted with their own demise.
"I think that everyone as a neutral probably knew that it'd be a good game," said Cook. "It turned out to be, but we conceded really poor goals today. When you give poor goals away in a game you're going to struggle to win it.
"You can speak about different parts of the game but what you must do after a game like this is pat Swindon Town on the back.
"They're a fantastic team, I love watching them and the way they play. I think everything about them as a club at the minute's good and I hope they go on and get promotion because I think they deserve it."
Two goals behind for most of the second half, the Spireites pushed forwards, but by then Cook felt the writing was already on the wall.
He said: "You can't come away and give these sides goals. I thought second half we acquitted ourselves really well and were probably in the ascendancy. We had more of the ball, put good balls in and created chances but the game was possibly gone then.
"It's a disappinting day for us today but we haven't had many. Again we thank our travelling supporters, we know how difficult it is for them and we look forward to a tie at Derby now in the FA Cup."
Injury was added to the insult of defeat when ten minutes from time forward Gary Roberts pulled up with what looked a reoccurance of his troublesome hamstring strain, confirmed by Cook after the match.
He said: "It looks like his hamstring, it doesn't look a good one, so that's a big blow for us. We'll regroup and we'll have a queit trip back to Chesterfield.
"We've been on a good run but you must have a bit about you when you get beaten."
