Domenic Costanzo (born 9 October 2001) is an Australian football player who plays as a midfielder for NPL NSW club Marconi Stallions.
Costanzo was born in Sydney, to Angelo Costanzo, who played in Marconi at the time.[1] He didn't play football until his father moved to Newcastle Jets where he would find his passion of football while watching his father train.[2]
Costanzo started playing in the youth leagues in NPL South Australia.[3] He eventually joined Adelaide United, where he would play in the reserve league until being released and joining Croydon Kings under his father who was Head Coach at the time.[2]
In 2018, Costanzo played for Croydon's senior squad where he made his senior league debut against Para Hills Knights.[4] He left to rejoin Adelaide United for a year until being released and rejoining Croydon in 2020. He became the league's second top goalscorer only losing to Adelaide Comets captain and former A-League Men player Allan Welsh.[5] His impressive form would earn him interest from A-League clubs and, ultimately, sign a scholarship deal with Adelaide United at the conclusion of the season.[6]
After being released, Costanzo went on trial with Newcastle Jets and soon after, rejoined Croydon for a third time before moving to NSW.[7] On 23 February 2022, Costanzo was announced to have signed with Marconi Stallions following in the footsteps of his father who joined the Stallions in the early 2000s.[8]
