Asia's top sports leaders on Friday refused to back Prince Ali bin Al Hussein's election challenge to FIFA president Sepp Blatter and insisted it is doomed to failure.

Asian Football Confederation (AFC) chief Shaikh Salman bin Ebrahim Al Khalifa told AFP there would be no reversal of the regional body's previous commitment to back Blatter.

He said all 46 AFC member associations were behind the controversial world soccer chief, despite the Jordanian royal's status as an AFC vice-president.
