Peter Reid said his time at Leeds United taught him he was losing touch.
Former Leeds United boss Peter Reid has said his time at the club showed him the shift in power between players and managers.
Reid managed Leeds in 2003, where he lasted seven months before being fired, with the club going on to suffer relegation.
Prior spells with Sunderland and Manchester City had seen him do better, even spending time as England under-21 boss before taking the Leeds job.
Reid said: "You can’t do now what I did in Premier Passions (a documentary filmed while he was at Sunderland) effin and blindin at modern players, they’d just down tools.
"I learned very quickly at Leeds. Mark Viduka’s reaction told me everything. I’ve laid into him and I could see in his eyes he’s thinking I’m a piece of *****.
"As they’re going out for the second half I’ve pulled him over and said, ‘hey listen I’ve only made you an example because you’re the best player’.
"I had to think on my feet. But that was the point I realised I couldn’t do that anymore."
Leeds was one of the last big jobs of Reid's managerial career, with a spell at Coventry City following.
At Leeds he won just six of 22 games, and just 10 of 31 at Coventry, a stint which again lasted just seven months before he was fired.
He since took charge of the Thailand national team before managing Plymouth Argyle in 2010 for 14 months.
His last managerial job was a brief stint in charge of Indian side Mumbai City in 2014.
