Spireites 'keeper Ryan Fulton knows his side need to show more of a cutting edge if they're to turn good performances into good results following the loss at Shrewsbury.
Jay O'Shea had given the visitors the lead in blustery conditions at the New Meadow, but two similar headed goals from corners saw the Shrews come back to claim a late 2-1 win.
The Spireites had dominated much of the game, but despite eight shots on target and ten corners were unable to turn their pressure into goals.
"I think we were the better team, in the second half especially," said Fulton "We had plenty of chances but we needed to get on the end of them and be ruthless.
"As a team you need to defend set-pieces and do the same at the other end with scoring them, that will win and lose us matches so it's something to work on in training.
"The wind played a part in the game, but we've got to do our job, me especially. You've go to keep your eye on the ball, keep focused. You can't change the weather so it's something you have to deal with."
Four League One games into his Chesterfield career and Fulton feels he is still developing, and enjoying the tutoring of his latest goalkeeper coach.
"I'm still learning lots, it's a different league, different players and different styles. We played Swindon who just keep playing the ball, while Shrewsbury were a bit different, they didn't try and play much it was just the longer stuff.
"Matt Duke's taught me a lot, he's been a round the game and he has his own way of doing things in training. He helps me a lot - now the main thing is to keep the ball out of the net and however you do that, it doesn't really matter.
"I'm still learning plenty and I'll keep learning all the time I'm here."
