Leeds United boss Neil Warnock is ready to revive his rivalry with Chelsea manager Rafa Benitez in tomorrow night's Capital One Cup tie.

The last time Leeds manager Neil Warnock heard from Benitez it was to threaten legal action.

Warnock has criticised Benitez several times since his Sheffield United side were relegated on the last day of the 2007 season, admitting he "hated" the Spaniard for fielding what he felt was an under-strength Liverpool team against Fulham a week earlier.

"I don't think I should get into that,' said Warnock. 'The last time I heard from Rafael he was threatening to sue me in an email if I mentioned it again.

"But enough water has passed under the bridge. I don't want to give you any more ammunition."
