One of Sydney FC's fan favourites is inching closer to leaving the club with Ali Abbas poised to join a Korean club following the Asian Champions League round of 16.

The Iraqi international enters the final month of his contract in May and appears unlikely to remain with Sydney FC next season as it's understood a high-profile K-League submitted a lucrative offer to sign Abbas in June.

The 29-year-old held informal discussions with the Sky Blues over the course of this year to extend his stay at the club, and Fairfax Media understands he recently received an offer of a one-year extension. As reported by Fairfax Media last month, the left-winger and fullback began looking at options abroad having attracted interest from Asia.

The Sky Blues are already guaranteed of playing in the Asian Champions League round of 16 despite having one group match to play. While his future is in doubt, Abbas will definitely be part of the Sydney team to play either Shandon Luneng or FC Seoul in their first ever knock-out match in Asian football.

Abbas joined Sydney FC in 2012 making 68 appearances in the A-League and recovered from what was a potential career-ending knee injury, making his comeback this season.
