Both Amini and Mooy came through the famous production line at the western Sydney school, that counts Harry Kewell, Jason Culina, Mat Ryan and Alex Brosque among its alumni. Despite the three-year age difference, they also appeared for the Australian Under-23s together.

Now they are battling it out for a place in Ange Postecoglou's midfield for the World Cup qualifier against Iran.

"I actually went to school with Aaron Mooy and played with him in the Olyroos so it's nice to be back with him," Amini said.

"I know a lot of the boys from the Central Coast Mariners days and the Olyroos and stuff so it's nice to see old faces. But it's a new step in my career and I'm happy to be here."

After representing Australia at Under-17, Under-20 and Under-23 levels, Amini is now in his first Socceroo squad. The midfielder, who left the Central Coast to join Borussia Dortmund in 2012, said it has been a long journey for him.

"It's very rewarding, I'm very happy to be here," he said.

"I'm very excited. It's been a long time but I'm very happy to be here. When I was 18 I moved to Dortmund. I have a very good experience there, three years there, and I enjoyed my time. Then it was time for me to start playing first-team football and of course I moved to Denmark.

'It's been a long journey for me and at the end of the day, it was for the Socceroos as well and to make my nation proud."

The AGF man is hoping to make his debut either against Iraq or next week against the UAE.

"I'm a ball-playing midfielder than can change the tempo of the game," he said.

"Hopefully I can show what I can do and make my debut. With Ange everyone has to be on their toes, no one knows whos in the squad or whatever. It's always about playing and playing well, then that suits himself.

"I'm just looking forward and enjoying this camp, and being happy to be here."

Australia are strong favourites against the Iraqis after their 2-0 win over them in September. But Amini is taking nothing for granted.

"I've watched all the games so far in the World Cup qualifcation," the 23-year old said.

"We're a favourite and a strong nation but when you're at away game in Iran it's going to be difficult. But I believe in us and I think we can get the three points here and take it with us to Sydney."
