Adelaide United have finalised their 23-man squad Hyundai A-League roster for the upcoming season, re-signing youngsters Mark Ochieng and Ben Warland.

19-year-old Ochieng and 20-year-old Warland have been given one-year deals, and the recent signing of Danny Choi as Marcelo Carrusca's injury replacement brings the list to 23 players.

Ochieng and Warland have kept their squad numbers from last season, 12 and 15, while Choi has chosen to take number 45.

New signings Sergi Guardiola and James Holland will wear numbers 9 and 25 respectively, with Sergio Cirio handing his No. 9 shirt to Guardiola in order to get the No. 11 shirt back from the departed Bruce Djite.
