There is an unnamed member of the squad, who keeps putting potatoes in Evans’ car’s exhaust, and the Scottish boss is still searching for the culprit.
He insists that he doesn’t mind the practical jokes though, as long as the team keep winning.
"Winning changes things," he said. "When you’re winning the atmosphere changes. I’m still looking for the guy who keeps putting potatoes in my exhaust, on the training ground!
"I’d have been looking for him in a different way if we hadn’t been winning games.
"Every time I have to get in the car, I’m getting potatoes out!
"I just see the players laughing, and they’re taking collective responsibility."
Leeds have won back-to-back games for the first time this season under Evans’ guidance, and they are on a high at the moment.
The Whites have beaten Cardiff City and Huddersfield Town in their last two outings, and they will be hoping that the international break does not destroy their momentum.
Leeds take on Rotherham United at the weekend, and a win in that match could lift them up into the top-half of the Championship.
That would represent significant progress for Evans, and would be sure to heighten optimism levels at the Yorkshire club.
