Nigel Clough gave his usual honest and frank assessment following Saturday's hard-earned draw against Leyton Orient.
The point gained - United's fifth in the last three games - lifted Clough's side out of the relegation slots in Sky Bet League One.
Liverpool loanee Conor Coady's first senior goal gave the Blades the lead but Dean Cox levelled for Leyton Orient, his half-volley looping into the top corner from the edge of the box.
"It is a shame really because all was going to plan and a screamer of a goal has denied us all three points," said Clough. "That's what it took to undo us.
"We have looked solid of late and are making teams score goals with a bit of quality."
The Blades chief added: "We kept two up front, didn't go too defensive because we wanted to win the game. We need to work on decision-making in the final third because as an away side you are not going to get too many chances.
"We are trying to build up confidence, are now three unbeaten and that helps. It has been a tough week, but we have picked up five points."
