Coach Aleksandar Janković invited Stefan Mihajlović, who at the time was a part of Red Star"s youth squad, to travel to Turkey with the senior team for the 2012-2013 winter break off-season. Mihajlović, at the age of 17, played his first match with the Red Star Belgrade senior team in a friendly against Eyüpspor, during which he scored two goals. He made his professional debut for Red Star Belgrade on March 9, 2013 in a SuperLiga match against Novi Pazar.
