BBC - Iran coach Branko
Ivankovic will quit after the World Cup, regardless of how far his team
progresses.
Ivankovic, 52, has blamed
media pressure as the reason for wanting to end his four-year reign.
He said: "I've faced unrelenting criticism over tactics, choice of
players and everything else for over four years.
"Even if we qualify for the next phase the attacks on me will continue.
Enough is enough."
Ivankovic arrived in Iran as assistant to Miroslav Blazevic and
succeeded his fellow Croat when they failed to qualify for the 2002
World Cup in Japan and South Korea.
He forged Iran into a strong side by blending experienced internationals
with talented younger players from the domestic league.
The formula saw Iran took third place in the 2002 Asian Cup, when they
lost to hosts China in the semi-final.
