The German head coach whose side are top of the Championship eight games in summed it up in two words: “Hard work.”
It applies to both the training ground and the pitch on match days.
Town head to Reading on Saturday seeking a seventh win in nine.
Wagner, whose side are two points ahead of Norwich City, who host Burton Albion, says feet remain firmly on the ground.
“Work in central to everything we do,” he said.
“We are a working club, a fighting club, and this is what the players are showing this season.
“They work hard at their jobs and for each other.
“In our system, all players are both attackers and defenders, and this takes work.
“When an opponent has the ball, I ask players to work as hard as possible to get it back.
“When we have the ball, they must be brave and want possession.”
Town have midfielder Philip Billing back in training after an ankle injury.
But forward Joe Lolley remains sidelined by a foot problem.
He isn’t expected back in full training for another 10 days.
