Warnock, who was in charge of Leeds from February 2012 to April 2013, is the interim head coach of Queens Park Rangers at the moment.
The Leeds head coach also has good words about Kevin Blackwell, who is currently the assistant head coach at QPR.
“I’ve known Neil for many years,” Evans told Leeds’ official website. “He’s been helpful to me in every shape or form.
“He’s always helped me with players and bringing teams in pre-season. He’s a man that I really do have a lot of respect for, and Kevin I know well.”
Leeds will head into the match against QPR on the back of a 1-0 defeat to Rotherham United at Elland Road in the Championship.
The defeat to Rotherham at home left the Whites 16th in the league table with 19 points from 17 matches.
The West Yorkshire outfit are just four points above the bottom three, and the risk of getting dragged into a relegation dogfight is still there.
Meanwhile, QPR, who got relegated from the Premier League at the end of last season, are 15th in the standings at the moment with 20 points from 17 games.
