Warnock, 64, certainly would not fancy swapping jobs with Mancini - because he would find it tough to deal with Premier League prima donnas.
Warnock said: "I had that for six months when I was in charge at QPR and I didn't enjoy it at all.
"And I certainly wouldn't like to have 22 players who all think they should be in the first team. Keeping everybody happy is a real problem for a top Premier League manager.
"So I don't think I would be able to cope with Roberto's job - and I am pretty sure he wouldn't be able to do mine, either.
"Managers like him need big financial support and that is why I feel he couldn't manage at Leeds in the club's current climate."
