The Rotherham United boss was discussing his time at Leeds United.
This weekend will see Leeds United travel to Rotherham for a Yorkshire derby which will see both managers up against former teams.
Steve Evans travels to the New York Stadium, where he once guided Rotherham to the second tier.
Warnock spent 14 months at Leeds United and had a somewhat tricky relationship with the Leeds United fans during his time with the club.
Speaking to talkSPORT this week (30/03/2016) he spoke briefly about his time at Leeds United – admitting it was one of the few regrets in his managerial career.
He stated that he felt he could have done good things at Leeds, if he was given the right investment by the club:
“That’s probably one of my few regrets. I wish I could have had more investment promised.
“I sold the lad (Robert) Snodgrass and it was said I could have some money out of that. I never got any, it changed within 48 hours.
“I think we could have improved then. We could have had a right go at it.
“That is a regret, but you move on.”
He is of course talking about the 2012 sale of Scotland international Robert Snodgrass to Norwich City. It was a deal that earned Leeds a fee reported to be in the region of £3 million by the Daily Mail.
That summer Leeds made wholesale changes to the team with the likes of Rodolph Austin, Lee Peltier and Luke Varney all arriving at the club for fees but performances did not improve and Warnock clearly feels he was not given the opportunity financially to push Leeds to the next level.
This weekend he will be hoping to continue his survival charge with Rotherham by getting one over on his former club.
