The squad land at their training base in Kazan today, fresh off of a 2-1 win over Hungary in Budapest last night.

Daniel Arzani was the star of the error-strewn show, emerging from the bench on 73 minutes and whipping in the opener, his first international goal, just a minute later.

After that, the 19 year-old Melbourne City maestro spent the rest of the match demonstrating his usual get-you-off-your-seat mix of tricks, flicks and direct running - just what van Marwijk had asked of him as the substitution was made.

"He was just telling me to do my own thing and to not be afraid to take risks or take players on. That's the kind of faith you need from a manager and I really appreciate that," said Arzani.

"The last couple of months have moved really, really fast for me and I'm still learning as I go. I'm just really happy with the way everything's worked out."

The truth is, while Arzani has no trouble assessing situations on the pitch, he's still getting to grips with what's happening off it. He is both the youngest player heading to Russia, and the first teenager Australia have taken to a World Cup finals.

"It's unreal - honestly, it hasn't really sunk in yet that I'm going to a World Cup," he said. "It's something you grow up watching and always dream of paying in.

"I'm absolutely ecstatic."

While Arzani produced the gods, Van Marwijk admitted Australia as a whole were not at their best in Budapest, but praised their attitude in forcing a winner after conceding a late equaliser to the hosts.

"I told them at half-time I wasn't satisfied. In the second half, in my opinion, we did much better. For a big part, we had control in the game," said the 66 year-old.

"You saw that they didn't think about settling for 1-1 - they wanted to win, and that's positive."
