While the Socceroos are still confident he will be able to play,Tilio’s arrival gives Arnold the opportunity to pull the trigger on a squad change,with FIFA rules giving him up until 24 hours before their opening game against France on November 23 (AEDT) to make any player swaps due to medical reasons.

A certain starter when fit,Boyle is one of a number of Socceroos players who came into campunder an injury cloud,along with skipper Maty Ryan (knee),attacking midfielder Ajdin Hrustic (ankle) and central defenders Harry Souttar (knee) and Kye Rowles (foot).

All those players trained on Tuesday afternoon (local time) — as did Tilio,who linked up with the Socceroos on Tuesday morning — but Boyle was nowhere to be seen.

Capped five times for Australia,Tilio was part of Arnold’s squad for June’s World Cup play-offs and September’sfriendly series againstNew Zealand but was overlooked for Qatar due to his benching for Melbourne City in the early weeks of the A-League season.

Tilio,21,did hit form in the later rounds and managed to squeeze out Andrew Nabbout — who started up front for the Socceroos in all three matches at Russia 2018 — from City’s starting line-up,but left his run too late to supplant the other players in Australia’s pecking order on the wing and earn selection.

However,Boyle’s misfortune could yet open the door for the opportunity of a lifetime for Tilio,who is seen as one of the most exciting young players of his generation in Australia.
