GWS star Zac Williams could be on the move with multiple clubs lining up for his signature, according to The Age's Jake Niall. 

Multiple clubs from Victoria and other states are interested in the 25-year-old's services after he turned down a five-year extension with the Giants at the end of last year. 

It opens the door for rival clubs to pounce, however, none of the interested teams have yet made a formal offer for Williams. 

Williams could choose to explore his options in the free agency period as a restricted free agent, however, GWS would have the power to match any offer.

Ii is possible the Giants could let Williams walk to free up salary cap, or may not have the funds to match rival offers.

Williams is expected to command offers over $700,000-a-season, a figure that could continue to go north with clubs willing pay more to get his services.
