After an already heavily-depleted Brisbane squad lost Luke DeVere and Jack Hingert to injury within the first 20 minutes and Danny De Silva gave Sydney the lead, it looked like all was lost for Darren Davies' men.

But Brisbane's young guns took the match full throttle in the final half an hour, showing the class academy that just won the Y-League Championship translates into A-League football.

After Tobias Mikkelsen drew the sides level, Dylan Wenzel-Halls' brilliant 90th minute strike gave Brisbane their first win under Davies' tenure, a win that he and the rest of his side believe has been a long time coming.

"Words can’t describe, I was cramping to be fair," Wenzel-Halls said. "One of the best games I’ve ever had. We’ve grinded and it feels great to get the win.

"I love going back to the crowd, they’ve supported us through thick and thin."

The Brisbane striker showed a lot of confidence in a cracking finish, but also in a cheeky tug on Rhyan Grant's mullet.

"He was telling me I go down too easy, and his mullet is a thing of beauty, I’ve never seen anything like it.

"I just wanted to run my hands through it."

Matt McKay was equally bullish after the match, after starring in a vastly unfamiliar centreback role.

"If Leigh Broxham can do it, I can do it," the diminuitive midfielder said.

"I’m proud to get that win, it’s been a long time coming, last week was horrible and we should have won. Backs to the walls, that’s what Brisbane Roar’s been about for the whole time I’ve been here."

He also took time to credit the debut performance of Brisbane Roar's youngest ever player, Isaak Powell, who put in a fantastic performance after coming on for Hingert.

"16 years old, it’s great for Isaak, I thought he did really well. He’ll be a great player for the future," McKay said.

"I was pretty nervous, but once I was out there with the lads they helped me out," Powell commented.

"I was all good, Matty beside me, Henrique in front of me. Hopefully I can play more games."

After breaking his coaching duck, Darren Davies was similarly enthusiastic about his team.

“We had Matty at centreback, a 16-year-old at leftback, it was just outstanding,” Davies said.

“ It speaks volumes of the character within this group.”
