But with Levein having been told to reduce the wage bill by £5m it could be the Foxes would be unable to meet Dublin's wage demands.
Leicester's confident start to the game was rewarded as early as the sixth minute when Dublin towered above a stationary Leeds defence to head Gareth Williams' out-swinging corner into the top left corner of Neil Sullivan's goal.
Sullivan then did well to block Stephen Hughes' close-range shot, before Williams fired Alan Maybury's cross into the side-netting as City continued to dominate.
Leeds struggled to contain inventive Leicester who again went close after 23 minutes when David Connolly drove a Hughes cross against a post with Dublin unable to force the rebound home.
And it was another flowing move that saw City double their advantage after 39 minutes.
Lilian Nalis nodded on Danny Tiatto's throughball for Hughes to cross into the six-yard area from where Connolly hammered home a right-foot shot.
Leeds - down to their last 16 fit players - posed more of a threat after the break.
Ian Walker did well to hang on to Clarke Carlisle's header from a Matthew Spring free-kick, but a comeback seemed even more remote after 65 minutes when Spring's 25-yard free-kick from directly in front of goal was high and wide.
But Leeds were offered a way back on 70 minutes when they were awarded a penalty.
Walker performed brilliantly to keep out substitute Marlon King's header but the rebound fell to Spring, who was then ruled to have been brought down by Patrick McCarthy.
King's penalty was well struck but Walker dived to his left to claw the ball away.
