The team consisted of twelve contracted youth positions with four overage players (from the senior squad) allowed to participate in games.

The side had initially contracted Football Superstar winner, Adam Hett, but had to be replaced for the campaign due to a season ending knee injury.

[1] In its first season Sydney FC Youth won the 2008–09 NYL Championship, with former Socceroo & NSL stalwart, Steve O'Connor as the coach.

The pair then went straight to a Grand Final match, of which Sydney FC Youth emphatically took out the tournament with a 2–0 victory at Hindmarsh Stadium, Adelaide.

Many of the Sydney FC Youth players in the Grand Final went on to have success for the senior squad or found a home elsewhere.

They included Vedran Janjetovic, Rhyan Grant, Matt Jurman, Antony Golec and Brendan Gan.

A few players from this cohort went on to play for the first team, including Dimitri Petratos, Nathan Sherlock, Joel Chianese and Blake Powell.

[3] To take up a more senior assistant role with the first team, Corica relinquished the head coach position for the 2011–12 season.

The season became Sydney FC Youth's worst performance in the team's five-year history, finishing ninth.

Unable to repeat this performance the following year, Corica again relinquished his duties as head coach to focus on his role within the senior squad.

Notable exceptions included Anthony Bouzanis, Aaron Calver and George Blackwood as they had also signed senior contracts and were ineligible for the tournament.

[11] The streak ended in somewhat unfortunate circumstances against Marconi Stallions as Sydney FC U21, after leading 1–0, allowed in two goals in last five minutes of the Round 12 clash to lose 2–1.

The teams also shares Sydney FC's club's training base at Macquarie University in North Ryde.
