Paul Okon's promising youngsters registered a memorable and dramatic victory against South American opposition at a tournament in the United States
After defeating Bermuda 3-1 in their opening game of the tournament, Paul Okon's men had to come from 4-2 down to defeat Chile to make it two wins from two in the round robin tournament.
The Young Socceroos initially went 2-0 up only to concede four times and find themselves trailing 4-2, before powering home with three goals to win the game 5-4.
The opening two goals for the Young Socceroos were scored by Marc Marino of the Australian Institute of Sport and Campbelltown City and Brisbane Roar's Devante Clut.
Chile replied with four goals to stun the Aussies.
Then, with the game seemingly out of reach, Adelaide United super-sub Awer Mabil popped up twice to level the match.
And Perth Glory's Italian-bound playmaker Daniel de Silva, who signed for Roma earlier this year, iced the cake with a winner to make it 5-4 in one of the most exciting games in Young Socceroos history.
It also extracted a measure of revenge on behalf of the senior Socceroos, who were defeated by Chile 3-1 at the World Cup in Brazil last month.
Mabil has now scored four goals in two games at this tournament after his brace against Bermuda as the Adelaide striker's star continues to rise.
Saturday's final game against the USA will be streamed live on US Soccer's website (kick off midday AEST).
Young Socceroos' starting line-up against Chile:
Paul Izzo (GK) (Adelaide United), Shayne D'Cunha (Blacktown City), Daniel Alessi (Western Sydney Wanderers), Riley Woodcock (Perth Glory), Hagi Gligor (Sydney FC), Jaushua Sotirio (Western Sydney Wanderes), Devante Clut (Brisbane Roar), Scott Galloway (Melbourne Victory), Chris Naumoff (Sydney FC), Liam Rose (Central Coast Mariners), Marc Marino (Campbelltown City).
