First, and most important, Brook is developing a big reputation with his talent on the pitch.

Australia defeated Malaysia 1-0 in the final of the Asean Football Federation (AFF) U18 Championship at the Thang Nhat Stadium in Ho Chi Minh City on Monday. 

It was a record-equalling fifth title.

And it was the 18-year-old’s coolly taken second half match-winner that helped secure the Young Socceroos the trophy.

It was made in South Australia with Louis D'Arrigo providing an expert assist. 

Given the injuries challenges Brook had last year, it was a sweet moment for the striker in the number 20 shirt 

Late in a tight clash, when it mattered, the former Gawler junior kept his cool to chip the on-rushing Malaysian keeper from a tight angle.

It sparked pandemonium from the bench and help win silverware for the green and gold.

But Brook has another talent.

The forward recently took inspiration from a family member.

Now back in Australia and still on a high, he explained more.

“I don’t mind getting around a bit of music and singing in the small amount of time I have off from football,” he told FTBL.

“During my injury last year, I decided to take some lessons with my sister’s music teacher.

“And I enjoy it, I do it for a bit of fun. It kept my mind off my injury.”

So, is the teenage Red any good?

Now that he’s part of the first-team squad, his initiation proved to be a showcase of his talents.

Though the rising star was keen to play down the crowd’s reaction when asked about the response from teammates.

“I won’t give my own opinion on it, but if we go off my initiation when I first signed, I think some of the boys were fairly impressed.

“That’s all I’ll say…” he added with a smile.

And there were plenty of smiles on the pitch after his deft chip helped win the AFF title.

“It was special. To score a goal in any final is special but this pretty special.

“Actually I missed a chance five minutes earlier that was easier. So that was playing on my mind.

“So when the next chance came, I couldn’t miss it," he said. 

The final against Malaysia had another interesting subtext with Aussie coach Brad Maloney pitted against Young Socceroo boss Gary Van Egmond.

The Adelaide United rising star said it was a tough tournament overall, with games in the Vietnamese heat coming thick and fast.

“With matches then recovery then another game every two days it was draining.

“Just one day off in between games, I’ve learned from previous national team trips how to use them wisely with massage and recovery.

“A lot of players hadn’t actually represented the country before, and I hadn’t met many of the boys.

“But to have a team gel so quickly, and want to fight for each other was really pleasing.

“But after the final, a lot of the boys are very physically and mentally drained and tired.”

Brook, along with Al Hassan Toure, is one of a clutch of young Reds coming through at Hindmarsh this A-League season.

It’s an exciting time for the squad under new Dutch coach Gertjan Verbeek.

And after debuting in the Asian Champions League two years ago (“that was a night I’ll remember forever, debuting for my home club”), Brook has his hopes set on a breakthrough season with the Reds.

“This year I’m looking forward to trying to get into the first team.”
