The 23-year old Brisbane-born forward has always had fairly big wraps placed on him but has failed to live up to lofty expectations which came after a prolific junior career which saw him dominate for the Australian U17 and U20 youth teams in the mid-2000s.
In Australia's domestic league over two seasons, the speedy Williams scored eight goals in just over 40 matches but was in a Fury side which were conceding goals and getting beaten heavily every second week.
Some of his finishes for the Townsville club were sublime and his creativity and pace were often too good for opposition defenders.
You could say that he is a similar player to former Palace starlet Victor Moses who is now with Premier League club Wigan Athletic, however, the England U21 international is a lot silkier than the Aussie. Where Williams can out-run his opponents and find teammates with pinpoint passes, Moses does it with a bit more finesse and obviously at a much higher level.
Just prior to the Fury folding, Williams joined Sydney FC for the Asian Champions League campaign in which he has started both games so far as the Sky Blues have manufactured two draws.
This could be one of the reasons why the Eagles have reportedly invited him to South London's Selhurst Park for a trial as new assistant Tony Popovic was a key figure on the Sydney coaching staff.
It remains to be seen if Williams will actually make the trip to the UK to link up with Dougie Freedman's Palace, and if he does, he may benefit from being in a more competitive environment which could bring out his best after maturing as a player back in his homeland over the past few years.
