"They have to have belief in themselves first and foremost. Just talking to Jamie McLaren on the phone the other day, you can tell that kid really believes in himself.

"It's my job to give them that belief on the field and to do what he does best.

"I know that they can score – they've shown it before. So you know when you have the quality and and you've shown that you can do it in the past, then it can be the mental aspect and it's one that we work hard on the fix."

He added: "[Arzani] is a very intelligent kid – he knows what his plan is, he knows what his goal is and he's got good people around him to advise him.

"The most important thing – and he's clear about that – is that wherever he goes, he has to play.

"He believes in himself a lot which is great. He believes that by going to Celtic, he will get to play more games in Scotland and be part of the Champions League squad, than he probably would here in Australia

"It's good to hear a kid have that confidence and belief in himself and I'm sure that he will do exceptionally well."

In the short term, Arnold revealed the FFA are lining up two friendlies in September – including a farewell for retired Socceroos legend Tim Cahill – and another in October ahead of the Asian Cup.

"My main goal is obviously the Asian Cup and we are current champions," he said.

"You saw how well Japan and South Korea  did at the World Cup so it's gonna be a wonderful challenge. 

"And it's about exposing people to that opportunity to play at the Asian Cup.

"In a lot of ways that is short term but for me I've always been a person that looks at the long term and I'm just excited to work with this group of players."

The relaxed coach even found time for a joke about his old club Central Coast Mariners trialling Usain Bolt.

He added: "Everyone says I need a goalscorer and Usain hasn't been capped yet by Jamaica so he might be a possibility..."

But he quickly added: "Okay, that was a joke!"
