Alan Knill praised the 'attitude' of the players, following Tuesday's deserved victory over Reading.
A brace from skipper Billy Sharp and a goal from Mark Duffy paved the way for the success at the Madejski Stadium, much to the delight of Chris Wilder's number two.
Knill commented: "It was a really good performance from the players. Everything we asked for and everything we expected, we got.
"We were disappointed after Hull and the standards have been set by the players not us, so when they drop below them it's right they're told and what a way to answer the questions.
"First-half we had chances, we should have been three up inside 15 minutes, but at least we're creating chances."
The assistant manager added: "The thing that pleased us most was the attitude, we want them to run around, compete and be aggressive because we know we've got some quality players.
"We play with an intensity and we find ways of winning matches regardless of how the opposition play."
