After failing to score a goal from open play at the World Cup, the Socceroos struggles in the final third were put on full display with Graham Arnold suggesting belief will be key to correcting it.
With all-time leading goal scorer Tim Cahill set to retire, the soon to be national team coach believes the Socceroos have the players to score goals, with mentality the main thing they must address.
"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.
"I think that's the big improvement that you've seen in England.
"A lot of the top sides now use sports psychologists for the players; there's a lot of negativity in social media around players and what they read. It can affect people.
"I think we've got the players there, but then it's about the belief and backing yourself and giving yourself the opportunity to make a big impact."
Under a pragmatic Bert van Marwjik, the Socceroos were relatively conservative in attack at the World Cup with Arnold vowing to send his side forward more freely.
"It's about getting enough men in the box to score goals," he said.
"There's no use getting one player in the box, you need three or four with good delivery but also the freedom to play in the final third."
Arnold refused to rate Australia's overall performance in Russia after watching on from the stands.
While not particularly critical of what he saw, Arnold did stress he will expect more from the side when he officially takes charge.
"I thought we made a good account for ourselves," he said.
"I expect greater when I go in. I'm looking to make a great impact on this team."
