Former Yugoslavia international Sinisa Mihajlovic has been confirmed as the new coach of Serbia.
The 43-year-old has admitted, however, that he will quit if he fails to steer the club to the 2014 World Cup finals in Brazil.
"I am completely confident we can reach the World Cup finals and I will step down if we fail," he told reporters.
Serbia failed to qualify for Euro 2012 under former boss Vladimir Petrovic.
