Warnock remains angry after the Liverpool boss sent out a second string team against Fulham last season - a decision which he insists was crucial to the relegation of his Sheffield United side.
Warnock told the People: "Benitez bugs me the most. He showed a lack of respect because Fulham were the worst team in the league and weren't going to get another point. I couldn't believe that Liverpool team, there were two players on the teamsheet we'd never even heard of.
"He'll never win anything else now Benitez, that's his lot. I don't feel anything for him now. What goes around, comes around. I've no sympathy at all and never will have."
