Really like your current first-choice team. Robertson is unproven at international level, but then he also hasn’t been given the chance to prove himself.
It’s interesting the large number of players who are injured/changed allegiances/not getting game time/lost form etc:
K. Yengi, C.Goodwin, Periac-Cullen, Triantis, Segecic, Luongo, Matthews, Farrell, Strain, K. Bos, Botic, Waddingham, Stama,J. Iredale, Carter, Milanovic, Tilio, Drew, Silvera, Arzani, Teague, Nisbet, Kalik, Devlin, Miller, Adamson. That’s a huge chunk of the Socceroos depth.
On the other hand you have the rise of Herrington, Trewin, Suto, Italiano, Okon, and others.
Agree that Arena wouldn’t accept a call-up. Suto seems to have scored most(all?) of his goals from centrally or the left with his left foot, so maybe not right forward? While I like Elder, he’s injured again and I don’t think there’s enough time for him to prove himself to Popa so Behich will be on the plane. Bennie, while he’s undeniably talented, also not enough first team action unfortunately.
