Western Sydney Wanderers will have to compete with offers from Europe to retain the services of first-choice goalkeeper Vedran Janjetovic, who could leave the club for abroad at the end of the season.

The 30-year-old is in the final four months of his contract with the Wanderers and could leave for free at the end of May as he is yet to sign a new deal for next season. It's understood the Wanderers are keen to keep Janjetovic, whom they regard highly and are continuing discussions over a contract extension.

However, the club is braced for the possibility of his exit after Janjetovic attracted offers from clubs in Belgium, Greece and Italy to join as a free agent in the European summer.

Sources confirmed his form this season has lead to a flurry of offers since December from a club in the Belgian Pro League, the Greek Superleague and an Italian Serie B club whose identity remains unknown. Janjetovic is eligible to move freely to a European club as he holds a Croatian passport.
