Why would you think that? He shows no signs of being an organised or competent manager. He might have been a good manager once (Average, at best in my opinion!), but he certainly isn't any more. He was effortlessly guiding Palace to relegation and he'd do the same here. He is, obviously, not a candidate.
When i was a child a friend of mine had his eyebrows singed off by a drunken stepdad. Warnock must have similar repeated memories daily when drawing on his forehead taches with a pencil usually used by a portly black chick in my office named Gloria. Warnock is not wanted by me in part for his eyebrowlessness.
Warnock has been a good manager, but so too for that matter have George Graham, Terry Venables and Ron Atkinson, but I doubt anyone would be suggesting them for a managerial position these days. The last success Warnock had was in getting QPR promoted 3 jobs ago, but he would have got them relegated had he not been sacked and would also have done with Palace this time around but for Parish's intervention, while his spell at Leeds did not go well. His time's up.
