Petković retired from professional football without ever playing for the White Eagles. In 2009, Serbia coach Radomir Antić praised Petković's success as an incoming 2009 Brazilian champion for Flamengo, but confirmed the player's too unlikely chances in being included for 2010 FIFA World Cup. Petković never had such expectations anymore, feeling himself too old as having 37 years: "I would like having ten years less to at least go to a World Cup", he said while celebrating his country confirmation to South Africa. He just kept some desire in playing a last friendly match for his national team.
