Chesterfield manager Dean Saunders said he felt sick after seeing his side turn a two-goal leading position into a loss at home to Wigan Athletic.
After a goal-less first half Dan Gardner lit things up with a superb curled effort, before Leon Barnett put through his own goal to make it 2-0. Barnet made amends with a smart volley and after former Spireite Craig Davies levelled from the spot Jordy Hiwula won the game in the last minute for the Latics.
Saunders was especially saddened as his side had looked so in control of the match before conceding the first goal.
He said: "It's a sickener when you're 2-0 up with ten minutes to go. We were comfortable but they're a good team and they looked dangerous all afternoon. Tommy Lee's made a few saves to keep us in it and their 'keeper's made a few saves.
"It was an open game, good to watch, we played some great football and I thought we we played really well.
"We were patient, got a great goal from Dan Gardner and then a good delivery from Dan Jones from the freekick, which is something we've practised, and we scored a second.
"Then they scored from a corner, which gave them a bit of hope. Ten minutes to go and it was second phase. It came in and then went out, a couple of headers and then a great finish in the bottom corner and from then threw everything forwards.
"They won a penalty which was dubious - Sam Hird says he got his foot on the ball - and then at 2-2 it crossed my mind to make a change but at that point you're sick at taking a draw after being two goals up."
The task for Saunders now is to pick up his troops this week ahead of the visit of Colchester United next Saturday, and the manager knows that won't be easy.
"It's going to take a couple of days," he said. "But then we'll come out and fight again against Colchester next week."
