Roma attacker Cristian Volpato has rejected a place in Australia's World Cup squad.
Aussie born and raised, Volpato also qualifies for Italy.
Socceroos coach Graham Arnold said: "Until 11 p.m. yesterday evening, I tried to convince Volpato to be part of the team. It wasn't my decision.
"He told me he wanted to think about it and talk to people close to him to see what would be best for his career.
"He later decided to turn down my offer to play for Australia in Qatar."
Roma coach Jose Mourinho stated this week that he wouldn't have to buy in January "because we have Volpato".
