Ivančić coached Sandra Perković, the Croatian discus thrower, whom he recognized as a talent in discus throw. In her first year with Ivančić, she improved her personal best from 32 to over 50 meters. After winning gold at the 2009 European Athletics Junior Championships, Perković became the youngest ever European champion in discus throw at the 2010 European Athletics Championships in Barcelona, and successfully defended her title two years later in Helsinki.
