Sydney: Dutch-based youngster Ajdin Hrustic was a surprise pick in Ange Postecoglou’s 30-man squad named Monday for Australia’s crucial World Cup qualifier against Saudi Arabia followed by the Confederations Cup. The 20-year-old Melbourne-born Groningen winger could make his debut in a squad that contains 24 overseas-based players and just six from the domestic A-League for the match at Adelaide Oval on June 8. Postecoglou selected six uncapped players and a set of brothers in Ryan and Dylan McGowan among his core group of European-based stalwarts — Mile Jedinak, Tom Rogic, Aaron Mooy, Massimo Luongo and Mathew Leckie. Former Everton star Tim Cahill, 37, and chasing a 97th cap, was also included.
