An ice-cool goal by Adelaide United's Argentinian import Jeronimo Neumann clinched a 1-0 win over A-League newcomer Western Sydney Wanderers on Friday night.
Jeronimo missed a contentious penalty but a minute later made amends with a deft finish as the Reds banked consecutive wins to open their season.
Wanderers midfielder Mateo Poljak went within a whisker of scoring the fledgling club's first A-League goal.
But Jeronimo's classy second-half strike dealt defeat to Western Sydney after its scoreless draw on debut against Central Coast Mariners last week.
Jeronimo was played into space in the 69th minute by a shrewd Iain Ramsay pass and the Argentine closed on goal as Wanderers goalkeeper Ante Covic made a make-or-break dash towards him.
Jeronimo coolly placed a left-footer past the approaching keeper and it trickled into the net to delight the 8,950 spectators at Hindmarsh Stadium.
A minute earlier, Jeronimo failed to convert a penalty after Adelaide winger Fabian Ferreira went to ground after jostling with Wanderers defender Nikolai Topor-Stanley.
While the penalty call appeared harsh, Jeronimo pushed his spot kick too close to Covic, who made a relatively comfortable save diving to his left.
The minute of action came after an opening half punctuated by skill errors and turnovers, with Poljak's near-miss in the 32nd minute a rare highlight.
Poljak launched a speculative 30-metre shot which caught Adelaide goalkeeper Eugene Galekovic off guard - the Reds captain parried with one glove with the ball bouncing up nicely for him to regather.
The Wanderers also had a late chance to equalise when Labinot Haliti found space in the box in the 88th minute, but his well-connected header was cut off by Galekovic.
