Hull City boss Ruben Selles praised his side's "excellent application" after they shocked promotion-chasing Hull City with a 3-0 win at Bramall Lane.
The Blades had lost just once at home all season and conceded only five goals in 13 games in front of their own fans prior to Friday's game.
The win moved Selles' side out of the relegation zone and two points clear of the bottom three.
"I feel really good because of the result but also because of the performance," he told BBC Radio Humberside.
"It's difficult to come and play and get points from here and I think we did a lot of good things today.
