AUSTRALIA boss Graham Arnold has detailed his communications with Celtic hero Tom Rogic amid uncertainty about his future.

The midfielder departed Parkhead this summer and is yet to find a new club.

With the World Cup fast approaching, Arnold is keen for Rogic to find a new home to build up preparations for the tournament.

"I get asked whether I've heard from him but you understand I have to leave him alone as well," Arnold said.

"I know what Tommy's like. I've known Tommy since 2010-11 and I'm not pestering him or sending him texts all the time.

"I sent one text quite a while ago to make sure that he was okay mentally and everything was fine and he replied 'yes' and that's it.

"I'm here to give advice if that's necessary but at the end of the day it's up to Tommy and his agent to find what's best for Tommy and then we as a national team, or me as the national team coach, work with him from that."

Celtic boss Ange Postecoglou spoke recently about his communications with Rogic.

"Has anyone spoken to Tom? No-one spoke to him when he was here for 10 years either, that's Tom," he said.

"I'd be more concerned if he was out there talking to people.

"Leave him alone, he's fine.

"He'll get his next move done and I'm sure he's in a great place ... I haven't been in contact with him, but the people I know say that he's got no problems."
