Troisi failed to make an appearance for the Newcastle first team and has been let go as Keegan looks to improve his squad.

"James Troisi has gone to play for Australia in the Olympics but he has not been offered a contract," said Keegan.

Despite coming through the system at Newcastle, Australia chiefs ignored the Adelaide native until this season, when he not only established himself as a crucial member of the U23 team, but also with Pim Verbeek's senior squad.
