Graham Arnold will become manager of the Australian national team after the 2018 World Cup in Russia.

This will mark the Sydney FC manager's second spell in charge of the Socceroos after he held the role for a year after Guus Hiddink stepped down after the 2006 World Cup in Germany.

Former Netherlands boss Bert van Marwijk, who famously guided the Oranje to the final of the 2010 World Cup, takes charge of Australia for the 2018 World Cup on a short-term contract after former manager Ange Postecoglu shockingly resigned after guiding the nation to 2018 World Cup qualification.

"It is a very great honour to coach your national team," said Arnold, who scored 19 goals in 56 as a player for Australia in the 1980s and 90s.

"It's a job I have always been interested in doing and I believe the timing is perfect for me.

"After today I won't be saying any more about the Socceroos until after the World Cup out of respect for Sydney FC and out of respect for Bert van Marwijk.

"I said at the time that I thought he was a great appointment to lead the Socceroos in Russia and everything he has done since has reinforced that view.

"I won't be getting under his feet but I will be cheering him and the team on from the stands."
