I disagree. I think he went to Europe previously, made the Australian squad, was a fringe player, went to the Asian Cup only to return and find he was now out of the first team squad in Greece, and as he was not an established international it was hard to get back in, and without being back in the team and playing regularly he drifted out of the Socceroos squad.
I doubt he'd want to make the same mistake again when he can stay put, in the shopfront window for Ange and playing in a winning team on the high profile stage in Australia to press his claim for a regular starting role with the Socceroos. THEN he can look to move and be much more valuable. I think that should be MUCH more valuable to him in the long term than the cash.
That coupled with the fact that China is a career dead end - no one seems to have made it there yet except end of career European superstars.
