Cacic, 65, will pen his contract with the Iranian football team in Istanbul, Turkey on Monday.
Branko Ivankovic has been named as Al Ahli of Saudi Arabia coach after leaving Persepolis in mid-June.
Cacic has been without a job after parting company with Croatian national football team in 2017.
Massimo Carrera, Alexander Nouri, Krunoslav "Kruno" Jurcic and Walter Zenga are the other candidates to take the helm at Persepolis.
Ivankovic led Persepolis to win Iran Professional League title three times. Under tutelage of the Croat, Persepolis also won one Hazfi Cup and three Super Cups.
