Nigel Clough admitted he was disappointed to only take a point from Saturday's Sky Bet League One clash with Walsall at Bramall Lane.
Chris O'Grady's first Blades goal put the hosts in charge of the game, but the lead lasted only three minutes as Tom Bradshaw levelled for the Saddlers an Clough felt that was the turning point of the fixture, despite United being the team pressing for a winner.
Looking back on the point, the Gaffer remarked: "It is another frustrating draw, because like at Fleetwood we have got our noses in front and not gone on to win the game.
"Walsall getting their equaliser so soon after Chris O'Grady's opener gave them a massive lift and went along way to the final result.
"We needed keep things tight for 10-15 minutes after our goal and really make them think about how they were going to get back into the game, but we haven't and paid the price."
Clough was delighted with O'Grady's performance, whilst the Blades boss also praised Che Adams and explained why Marc McNulty, Louis Reed and Florent Cuvelier weren't able to start the game.
The Gaffer continued: "We are delighted with what we have seen from Chris in his 90 minutes against Fleetwood and Walsall and he has shown he will be a real handful for defenders in League One, but it was still vitally important for him to get that goal.
"It was a brilliant ball from Jose (Baxter) and a great finish from Chris, but it is his whole round game that allows us to play with a front two when he is in the team because he works tirelessly.
"There is a lot of work to do with Che (Adams), but he did well on his full league debut and you can clearly see the lad has bags of raw talent.
"Che is versatile, he played up the middle for Ilkeston, so it also gave us the option to switch him with Jose. Ideally we would like to get Jamie Murphy playing from the left, but Che is more at home on that side.
"Marc McNulty was carrying a thigh injury from Tuesday night, that's why he didn't start and Che offered us fresh legs as much as anything else. He won't play every week but he'll certainly be in and around the first-team squad for the remainder of the season.
"Louis Reed and Florent Cuvelier were the same, they were feeling things from midweek."
