The 23-year-old Australian attacker enjoyed a stellar 2011-12 season at Kayserispor netting 10 times, before they finished their Super Lig campaign in 11th place last weekend.

However, Kayserispor announced on their club website on Friday that he had walked out on the club following the conclusion of the season.

Kayserispor statement read: "Troisi left the club without permission and as a result the club has decided to complain to FIFA."

Troisi had been linked with a move away from Kayserispor during the January transfer window after a pay dispute with the club.

It is understood, Troisi's wages were paid late and he had received advice from the Professional Footballers Australia.

The eight-time Socceroo, who started his professional career with English club Newcastle, joined Kayserispor from Genclerbirligi before the 2009-10 season on a four-year deal.
