Assistant Manager Andy Crosby felt the Blades were full value for the 2-0 victory over promotion chasing Walsall at Bramall Lane on Saturday.
First-half goals from Chris Basham and Billy Sharp paved the way for the success over Jon Whitney's Saddlers, who had previously only lost one on the road in the league this term.
And it was United's desire and commitment, along with their ruthlessness in the penalty area that earnt Crosby's praise.
He remarked: "We performed really well and deservedly won the game
"After Southend, we were written off by many, but we spoke about winning the next seven games and seeing where that took us, we have made a good start.
"The fans demand effort first and foremost and we won the majority of our man for man duels, we applied pressure on Walsall and that created an atmosphere.
"We controlled the game and enjoyed plenty of possession in Walsall's half which was our aim. When our front players defend as they did, we tell them they will get more chances because we will win the ball higher up the field and the opposition won't be as organised."
The former centre-half added: "Scoring first always helps, so to get two in front by half-time gave us a massive confidence lift. Both goals were excellent for differing reasons.
"The first one came from a brave header from Chris (Basham) at the back post from a terrific ball in from Matt (Done) and the second was an excellent finish from Billy (Sharp) after Bash went from scorer to provider.
"Both with and without the ball we dominated the game for 75 minutes or more and that's really pleasing."
