Michael Doyle admitted Saturday's draw with Oldham Athletic 'felt like a defeat'.
Nick Blackman's second-half penalty looked to have put the Blades on course for a third consecutive win, only for Matt Smith to snatch a point for the Latics deep into stoppage time.
The Blades skipper was understandably deflated with the result, United's sixth 1-1 draw of the season, and insisted performances must improve, particularly at Bramall Lane.
Doyle commented: "We weren't at the races first-half, we didn't get on the ball and we never played with any real tempo.
"As players, myself included, we must look at this and start games on the front foot, especially at home with the backing we receive. The supporters were fantastic again.
"It is frustrating because we weren't near to the standards to which we aspire and simply we have to improve.
"I am not being arrogant, but every draw this season, with the exception of Scunthorpe, has felt like a defeat.
"I'm not going to deny it, not for the first time this season I feel like we have lost."
