Chris Morgan believes United's frugal defensive record has been instrumental to the current seven-match winning run.
Speaking ahead of the Blades Sky Bet League One clash with Peterborough United, Morgan remarked: "Clean sheets give you the chance to go on and win the game.
"Personally, speaking as a player, I used to love a 1-0 win, especially away from home when you have to defend and be resolute for long periods.
"It has been a real team effort on and off the pitch and everyone deserves some credit, but ultimately it is the players that have gone out there and put what we have practised into game situations.
"The Gaffer wants to play attractive, attacking football, but we don't put the ball at risk. It is about knowing when and where to play.
"He wants the back four to defend first and foremost, but he wants them to be comfortable on the ball too."
Morgan reserved special praise for the Blades two centre-halves following the win at MK Dons on Saturday, adding:
"I thought Neill Collins was terrific at the weekend and Matt Hill proved how valuable and reliable he is when called upon, deputising for Harry, who has won some many headers in many of the previous victories.
"Collo really stood up on Saturday though, without Harry at the side of him. They have a tremendous understanding and a really strong partnership that has been formed over a few seasons."
