This time he shared the limelight.
Injuries and flutter have plotted against Baba Diawara and George Blackwood since joining the club last season, forcing Marco Kurz to look at all options.
The unconvincing returns with Ben Halloran by the center led the German to Stamatelopoulos and, on his return from the Youth Socceroos post, the teenager tried his luck.
Stamatelopoulos, who is only 19 years old, has demonstrated flawless fluency by performing a perfect center at the first post to allow Adelaide's star man to head to in the first match.
Seven minutes later, the young striker scored the second goal of his fledgling career in the Hyundai A-League. He followed a breakaway and brought the crucial touch to Goodwin's disinterested pbad.
Everything happened in 16 minutes, suggesting that Kurz has come up with the best candidate to complete his main attack weapon.
Key men thrive in professional performance
As for Goodwin, Caltex Socceroo, who has three caps, has scored an incredible eight goals in seven competitive games this season. He then beat Ben Kennedy on a free kick.
Isaias was also among the top performers in Adelaide, recording two badists while taking possession of the ball nine times overall.
When the Reds are functioning fully, it's usually because the heartbeat of the captain and the midfielder is at its best.
