Blades boss David Weir remains adamant that the Blades are making positive strides forward, but understands the frustration of the supporters following last week's defeat at Rotherham.
United's first-half performance drew praise from the manager, who believes the Blades deserve more points than the four they have from the opening six matches, but concedes the second-half showing at the New York Stadium was unacceptable.
Despite the reversal against the Millers, Weir is upbeat about Saturday's trip to Brunton Park to tackle managerless Carlisle United.
The Gaffer said: "I can appreciate how the fans felt after last Saturday because there would be something seriously wrong if we didn't hurt after the second-half showing.
"I can assure them that the management staff and players were down just like the supporters and rightly so, because we should have won that game from the position we were in.
"This week we have been working tirelessly, as you would expect, to eradicate the mistakes and improve other aspects of our game to try and make us successful at the weekend.
"People keep asking about changing our philosophies and formation, but we believe, in time, if everyone remains patient, that this way gives us the best chance of winning matches on a consistent basis, although we aren't naïve enough to think that we can't change. We remain flexible in our approach."
Weir added: "I honestly believe we have deserved more than we have achieved in our first six league matches, but we are where we are.
"I wouldn't be here if I didn't believe in this group of players and I think we are one result away from getting somewhere near the high standards we have set ourselves.
"Success was never going to happen overnight, though, and although we know we need some positive results soon, everyone has to remain patient."
