Wednesday put on their best performance for months against their arch rivals from up the M1 and got their first win of the season thanks to a Chris Eagles goal.
Richard Wood won many plaudits and arguably had his best game in a blue and white shirt but in fairness to the back four, they all played well as a collective unit.
Sturrock wanted his players to play like they did last season - without fear and with a high tempo and they did just that.
He told the club's official site: "In the first half everything we'd done on the training ground suddenly clicked into place. You've got to give credit to Leeds. They caused us all sorts of concern and chucked a lot into our box after the break but defensively we were absolutely magnificent."
The supporters created a great occasion and the noise inside the stadium spurred on the players.
"The atmosphere was incredible," added the Owls boss, "to have nearly 30,000 on a Tuesday night is amazing. They made such a noise you didn't hear the Leeds fans all night."
