Chris Morgan is demanding a fast start from the Blades when Port Vale arrive at Bramall Lane on Saturday:
"I want the players to believe in themselves, we can't keep telling them how good they are, they need to go out there and show that to the fans," said United's interim manager. "The lads have proved what they are capable of; the second-half showing last week must give us some momentum."
Morgan continued: "We have trained all week at a high tempo, despite it being a difficult week in terms of preparation and wondering whether or not a new manager is about to walk through the door.
"I made a conscience decision with regards to the plans for this week; whatever happens the lads must be ready for a tough game against Port Vale on Saturday afternoon.
"We have put a few ideas across to the players in terms of how and where we need to improve. The lads are together and the confidence will come from within.
"I am enjoying the responsibility of being in charge and can't praise the lads enough for their application on the training pitch. Whoever comes in to this club as manager has a fantastic opportunity, the only way is up."
Ahead of Saturday's clash, Morgan is looking forward to coming up against his former central defensive partner, who will be in the opposing dug out.
The interim boss added: "I have kept in touch with Rob Page since our season together as players. He is genuine football man and a true gent off the field.
"Like myself he has looked after his career off the field, we have both ticked all the boxes and are ready to be managers in the future.
"He is a top fella, when we were both linked with the job in the summer people thought it might cause us problems, but we are both professional and we have remained good friends."
