I would like to know the last Australian player who has played for 1 big European club for more than 3-4"years, even in the golden generation most of our player's were playing at low level epl clubs. 

Cahill played for a half decent Everton team, while the likes of Viduka had 3 average EPL clubs bar 1 year at Leeds. Neill at Blackburn & West Ham relegation candidates, Kewell would of been the one if not for injury.  These are some of our best ever player's & people think Celtic is below Rogic.

It sounds to me like people in Australia think Celtic are the lucky ones to have Rogic, I think it's Rogic, who is lucky to have Celtic.
