Sydney FC boss Graham Arnold has ruled himself out of contention to lead the Socceroos at this year's World Cup, but has left the door ajar to coach Australia in the future.

As reported in the Herald yesterday, Football Federation Australia is keen on the idea of appointing a high-profile foreign manager on a short-term contract for the World Cup and then replacing him with a permanent coach - possibly Arnold - after the tournament in Russia.

Arnold's announcement yesterday that he was committing to Sydney FC for at least the rest of the domestic season confirms that approach and will also come as welcome news for nervous Sky Blues fans.

"I am committed to Sydney FC and 100 per cent focused on seeing out this season and winning two more trophies for this great club," Arnold said in a statement yesterday. "I can confirm I will not be coaching the Socceroos in Russia."
