Blades boss Nigel Clough praised United's second-half performance in Friday's 1-1 draw with Notts County, but was understandably frustrated to concede from a corner again.
Jamie Murphy's bullet header earnt the hosts a deserved point, after County defender Mike Edwards has volleyed the Magpies in front from a Gary Jones delivery with Mark Howard making a rare error from the corner.
But Clough was encouraged with what he saw after the interval, although poor decision making in the final third was his main frustration post-match.
The Gaffer said: "In the second-half we were spirited, played with urgency and created enough chances and opportunities to win the game.
"But it is worrying that it takes us falling behind to another poor goal in the first-half of a game, to make us start playing on the front foot.
"We lacked that bit of composure and quality with the final pass in the second-half and we were turning down chances to cross the ball as the game progressed and that drives us mad.
"In training we work on getting the ball out into the wide areas and getting runners across the near post, but for whatever reason we aren't translating that into game situations at the moment, but it will come."
Of his goalkeeper and the performance of the visitors, Clough added: "Mark Howard came in at half-time, held his hands up and apologised, he simply missed judged the flight of the ball and unfortunately we were punished on another day we get away with it.
"You can see why Notts County like Oldham last Saturday are doing well and unbeaten on the road though, They stop you playing first and foremost then are a real danger on the break and from set-pieces as they proved."
