Chesterfield manager Danny Wilson admitted his anger after the Spireites conceded a late winner to lose 2-1 at in-form Bury.
The hosts had the better of the first half but Chesterfield came in level at half-time after Zeli Ismail’s 42nd-minute opener was cancelled out by Kristian Dennis three minutes later.
The Spireites then spurned several opportunities before Tom Pope condemned Chesterfield to their third defeat from five away games in League One.
“I’m angry because I think we had enough opportunities today, the second half in particular,” said Wilson.
“We weathered a lot of pressure in the first half and got through to half-time. We went a goal down but came back with an equaliser fairly quickly.
“Then second half I thought we took over. We had good possession and got into some fantastic positions but just frittered it away without even worrying their keeper.
“That’s what has upset me more than anything. The decision making when we were on the ball was very average and we’ve got to get better than that.
“When we’re in positions like that in games, and you get opportunities, if we don’t take them it’s going to keep pressure on the back four. I think they’re entitled to look at the strikers and say ‘you’ve got to start sticking those balls away’.”
However, Wilson feels his defence should have dealt better with the 89th-minute winner, as Pope headed home from Tom Walker’s diagonal ball into the box.
“We know what Pope’s like,” he added. “The two centre-halves lost him and he pulled onto Liam Graham, so it was no contest in the air.
“We shouldn’t have let him get into that position. We’d dealt with it all game until then and we paid the price for it.”
