Choi, who has been heavily linked with a move to Adelaide United, produced a special strike to open the scoring in the clash at Leichhardt Oval.

Blacktown added two second-half goals to seal, with substitute Patrick Antelmi netting on 72 minutes.

Choi rounded out the triumph with an 86th minute strike, providing some redemption for the Demons who lost last seasonโ€™s Grand Final to Bonnyrigg White Eagles.
