Fresh off a move to EFL Championship club Middlesborough FC, Sam Silvera earns his first Socceroos call-up, where he will be joined by Ashley Maynard-Brewer (Charlton Athletic FC), Tom Glover (Middlesborough FC), Scotland-born defender Cameron Burgess (Ipswich Town FC)  and Alessandro Circati, who returns for his second senior national team camp after seeing plenty of game time with Parma Calcio 1913 in Serie B. 

The new faces will be joined in a squad that features experienced stars Mat Ryan (AZ Alkmaar), Aziz Behich (Melbourne City FC), Milos Degenek (FK Crvena zvezda), Mitchell Duke (Fagiano Okayama) Jackson Irvine (FC St Pauli) and Mathew Leckie (Melbourne City FC).

“Playing Mexico is a great opportunity for the entire group, allowing us to not only test ourselves against quality opposition, but also familiarise ourselves with playing in the United States as we look towards 2026,” Arnold said.  “We’re coming up against top Central American opposition in front of what I’m sure will be a lively home crowd, and I’m looking forward to seeing how the squad approaches and responds to that challenge. 

“We’ve brought several younger players into this camp to give the coaching staff a glimpse at how they can perform both within our system and on the international stage. We’ve closely monitored the form they’re bringing from their clubs, and I’ve been really impressed with what I’ve seen overall. 

“The new members of the squad will have the benefit of working alongside many of our established, senior players, who will play an important role in instilling the values and principles of our group.

“With World Cup qualifiers beginning in November and the Asian Cup in January 2024, these moments that we can come together as a group become all the more valuable.

“These next three games allow us to provide valuable match minutes to players we want to see more of and, alongside the [Subway] Olyroos also playing during September, helps us understand the overall depth of our squad looking ahead.
