Thomas Deng has signed a one-year contract extension with Melbourne Victory.
Deng will now be a Victory player until the end of the 2019/20 campaign.
The 21-year-old centre-back has made 38 Hyundai A-League appearances for Victory since making his debut in November 2015.
Deng also spent a year on loan at Dutch giants PSV Eindhoven.
The Kenya-born defender was rewarded for impressive club form with a Caltex Socceroos cap against Kuwait last week.
He came on as a second-half substitute in a 4-0 friendly win that served as important preparation for the AFC Asian Cup 2019.
