New Socceroos coach Graham Arnold believes the national team's goalscoring woes can be solved between the ears.

Speaking for the first time since succeeding Bert van Marwijk in the top job, Arnold paid tribute to Australia for giving a "good account" of themselves at the World Cup in Russia, but also expected better things to come now that he is in charge.

The Socceroos failed to score from open play in their three matches against France, Denmark and Peru, with their only two goals coming from Mile Jedinak penalties.

"A lot of it these days is about the mind and what the mind tells you, and the mental aspect of the game," Arnold told Macquarie Sports Radio.
