Lyle Taylor insists United's start to the season remains very much a work in progress.
"We're a long way away from being where we want to be right now," the former Falkirk centre-forward said. "But there's a lot of change going on and so that was always going to be the case.
"We know we've got to improve everything that we do but we're moving in the right direction and working really hard behind the scenes to make sure we get there sooner rather than later.
"Being honest with ourselves is a crucial part of that. And we're all very honest with each other here. If someone isn't doing their job properly then they are told. They are told by the rest of the lads in the dressing room but that's the way it's got to be. That's the only way you improve.
"It's not just about the 11 players who begin a game. That goes for the whole group."
The striker was cruelly denied his first competitive goal as a Blade at the weekend, a goal which would have probably won Saturday's clash with Colchester United.
He added: "The manager here has shown a lot of faith in me. He's backed me by putting me in the team and now it's up to me to repay him for that by producing.
"I know I've got plenty of work to do. I don't deny that. But I've also got a lot of belief in myself so I'll get there.
"It was bitterly disappointing that the offside flag denied me the winner on Saturday."
