Petković began his career with FK Vojvodina with which he played excellently in the 2006-07 Serbian SuperLiga season. Foreign clubs became interested in his services and he subsequently signed for Gençlerbirliği S.K., where he got less playing time and was loaned to two different clubs. In the summer of 2009, he signed with Eintracht Frankfurt, but again only managed to play on an infrequent basis and was loaned out to FC Tom Tomsk and Al-Ahli (Jeddah) before coming to sign for Red Star Belgrade in 2011.
Red Star Belgrade
Petković signed a two-year contract with Red Star Belgrade on the last day of the summer 2011 transfer window.
On 19 September 2013, Sydney FC announced that they had completed their squad for the 2013/14 season by signing Petković on a 1-year deal. After completing the move, Sydney FC manager Frank Farina stated: "I am expecting big things from him this season and believe he will have a big influence on the squad." Petković made his debut for Sydney FC on 11 October 2013 at home to Newcastle Jets where Sydney FC won 2–0.
