Nigel Clough is looking forward to Tuesday night's clash at Oldham Athletic, as United look to make it seven games unbeaten in Sky Bet League One.
But United will face a Latics side that themselves are looking to take their unbeaten run to nine matches, a run that began in mid March.
Ahead of the Blades heading over the Pennies, Clough said: "Oldham play in a similar manner to how Lee (Johnson) played during his playing days.
"He liked to get the ball down and keep it on the deck and Oldham have stuck to their principles throughout the season, thankfully for Lee it has worked out for him and his players.
"They are eight games unbeaten and from fighting relegation they are closer to mid table than the bottom four, so like us they deserve a lot of credit, although they are a very competent side on their day and a re probably better than the table has suggested for long periods."
The Blades boss, who signed his Oldham counterpart as a player during his spell in charge of Derby County, identified two players who United will need to keep in check in Lancashire.
Clough concluded: "Oldham will want to finish on a high and like us they will want to take some momentum into next season.
"Gary Harkins is a good player from wide areas, whilst for a young lad Jonson Clarke-Harris certainly puts himself about up front.
"They are a solid and honest side who will make you work very hard for anything you get.
"We had Lee (Johnson) on-loan at Derby County and I am not surprised that he followed in his father's footsteps and entered management, he was always a good organiser and communicator as a player."
