George Long has hailed the impact Nigel Clough has had on the Blades since taking over in late October.
Speaking on BBC Radio Sheffield, the United goalkeeper commented: "The new manager should take a lot of credit for the upturn in results, along with the coaching staff he has worked tirelessly to get his demands across to the players.
"We have reacted positively and our performances have been a lot more consistent. We are picking up points in the league and have got through to the third round of the FA Cup."
Tightening up defensively has also aided the Blades' haul of 11 points from the last seven games, according to Long, who added:
"We have been solid as a team and, to be fair to the strikers, it has started from the front. The biggest confidence boost for me is consecutive clean sheets for the first time this season.
"As a goalkeeper it is fantastic to know you have got two strong banks of four in front of you. It makes you feel the team is impenetrable."
