FK Crvena Zvezda have sacked coach Vladimir Petrović and replaced him with the club's director of youth, Ratko Dostanić, following a 2-1 defeat by FK Metalac on Saturday. Appointed last summer, Petrović guided the Belgrade outfit to the top of the Super League, two points clear of rivals FK Partizan, and into the semi-finals of the domestic cup. However, a second league loss of the campaign has prompted a return to the 50-year-old Dostanić, who led the side in 2004/05.
