Rogic is one of the Socceroos key players and one of the most technically gifted midfielders Australia has produced, but after a lengthy spell on the sidelines at Celtic, it appears the playmaker is set to cash in on a move to Qatar.

The transfer - to a yet unnamed Qatari club - is rumoured to include a transfer fee worth around $7 million and Graham Arnold, talking to the Sydney Morning Herald, admitted the current climate favours the super rich.

"At the end of the day it's his career and we're here to advise him and speak to him about it," Arnold told theĀ Herald.

"The competitions in the Middle East are coming on very, very quickly and they're very strong, and with a lot of good players."

Despite the midfielder's lack of game-time, it's a surprise move for many given the 28-year-old's strong form when he has been selected, his legendary status in Glasgow, and his love for the club.

Rogic had only recently appeared to commit his future to Celtic when he spoke openly about wanting to remain at the club and fight for his place.

Arnold believes that the most important factor for the national side is Rogic enjoying his football, wherever that may be.

"The most important thing for me is that Tommy gets the smile back on his face and the enjoyment back in his game, and that he's also going to play football," Arnold continued.

"At the moment at Celtic, it doesn't look he's going to play much and he's had a season last year of on-and-off playing. The year before that, he had a lot of injuries."
