Danny Higginbotham feels United's togetherness will be crucial as the promotion race in League One gathers pace.
The experienced defender, who arrived at Bramall Lane on New Year's Day, says the unity amongst the players and management can only aid the Blades push for promotion.
The 34-year-old puts United's current good form down to the manager, who Higginbotham says puts all his trust in the lads to perform:
"There's a real spirit here. That became evident to me really quickly.
"You always need that and people work that extra bit harder. We work professionally and are ready to look at the small details, which can make a big difference.
"There's been a definite shift in emphasis recently, too. The manager encourages us just to go out there and trust ourselves. He provides us with the information on the opposition, but also trusts us to do the right thing and to be able to work things out for ourselves on the pitch."
Higginbotham, who thinks the Blades have an excellent blend of youth and experience, believes the extra responsibility the players are being given aids performances.
The versatile former Stoke man, added: "We've got people of all ages who know the game and who know what's required. You've got to be able to react to how things shape up during a game.
"But when are given that type of responsibility, it's a good thing and brings out the best in people, as far as I'm concerned."
