George took a pot-shot at the standard and structure of the A-League and went into great detail about how Victory players celebrated their grand final win earlier this year, lauding them for their "next level" approach to partying.

The 31-year-old attacker laid it all on the table in a wide-ranging, brutally honest and funny article with Vice Sports.

George seemed surprised that Victory was even in championship contention after finishing the regular season in fourth place, 23 points behind premiers Sydney FC on the ladder - a perspective shared by many foreign players who are unfamiliar with Australia's grand final tradition.

"We had a week just partying. Crates of beer in the locker room... those teammates of mine have boozed all week," he said.

"What do those Australians is really next level. Those guys were in that week starting at ten o'clock in the morning to drink.

"Man, they know how to party there."

George criticised the standard of the A-League as "not very high" but said he enjoyed his season with Victory and the relaxed Australian lifestyle.

But it will likely be his last in Australia, claiming Victory had not "fulfilled their commitments" to his agent by offering him improved financial terms to stay.

The club refuted that on Thursday while confirming his departure, saying George had turned down a "substantially improved" contract to explore other opportunities.

George, who is in talks with other overseas clubs as well, said he would only return to the A-League if presented with a compelling financial offer to compensate from being "so far from home."

Victory will also be without Williams next season after he was sold to Saudi Arabian club Al-Qadsiah on Thursday.

Williams, 29, was contracted for another year but will take up a Middle Eastern payday as he moves towards the latter stages of a career that has been blighted by injuries.

It leaves coach Kevin Muscat with plenty work to do on the recruitment front after the recent departures of Besart Berisha to Japan and James Donachie to South Korea.

It's understood Muscat is lining up former Victory stopper Nick Ansell to partner Thomas Deng in the centre of defence next season.

Overseas reports also suggest Melbourne has signed Dutch midfielder Danny Holla, who spent last season at relegated Eredivisie side FC Twente.
