Dean Saunders said his Chesterfield side did everything but score against Sheffield United.
The Spireites saw much more of the ball than the Blades and had the edge in all but one of the stats at Bramall Lane.
But goals at the start of either half from former Ilkeston FC prospect Che Adams gave United a 2-0 win in Saturday’s derby.
Saunders said: “I’m disappointed with the result but not the performance. I thought we played really well. I thought we dominated the game from start to finish.
“We gave them two sloppy goals right at the start of the game and right at the start of the second half, which we’ve talked about. Apart from that, I can’t complain.
“I thought they were excellent. Sometimes you don’t get what you deserve.”
Saunders rued missed opportunities in Tuesday night’s Capital One Cup tie against Carlisle United and voiced similar tones.
“How we’ve not scored today, I don’t know. We’ve had 14 corners, hit the post, hit the bar and we dominated possession through the game,” he said.
“The were counter attacking us. But you’ve got to score otherwise it gives them hope. We just didn’t get what we deserved. I said to them they’ve played really well.
“We can always learn from it and sometimes when you play against teams like that, we might just need to tighten up.”
Striker Lee Novak amde his first appearance for Chesterfield just 24 hours after signing on a season long loan from Birmingham City.
“He’s a class player and better than this league so I’m sure he’ll get goals. He’s a willing runner and I thought he played well,” added Saunders.
The Spireites have an opportunity to return to winning ways on Tuesday night when they travel to Shrewsbury Town.
“It’s a chance to put it right,” he said. “We’ve not got the result we wanted here but we played well last week. I thought we had 19 attempts against Barnsley, 26 against Carlisle and I don’t know how many we’ve had today.
“The final pass wasn’t right first half, the final cross wasn’t right and if we had a little bit more quality aruond the box to pick out Sylvan (Ebanks-Blake) and Lee (Novak) a bit better we might have gone on to win the game.”
He added: “There’s a long way to go and I’m learning as we go along. We’ve got to find the formula that gets us results against the big teams as well as the smaller teams.”
