"Growing up, there were four-on-fours in the backyard but it was proper; tackles were flying in and nobody held back," Chris said. "It will probably be like that tomorrow night."

Despite the age gap, the Triantis brothers never went easy on each other at home. They both shared the same goal of playing professionally.

"When I was young, he was very hard on me," Peter said. "He was critical, which is important. But he was also my number one supporter and always backed me. He still tells me how I can improve and when I don't play well, but he's always there for me and helping me out. I've worked really hard and he's the main reason."

Peter grew up watching his older brother from the sidelines at Belmore Sports Ground, and following his forays in Europe, which began in 2003. Chris left Australia to play with FC Metz and Middlesbrough before returning to captain Sydney FC's first ever youth side to an inaugural NYL title. He is no longer in the A-League, but said there was still a sense of pride in seeing his brother hold the midfield for the Sky Blues.

"Pete's a great player," Chris said. "He was one of our main players at Olympic even though he was young then. It was nice to play with him but now he's pushed on, which I'm happy for him because he's worked very hard for it."
