UAE outfit Al Ahli are preparing to make Beşiktaş striker Demba Ba a €10 million offer according to Fotomaç.
The Senegalese international has also been closely linked with a move to Chinese giants Shanghai Shenhua.
Ba worked alongside Bilic last season at Beşiktaş and scored a career high 27 goals in all competitions for the Black Eagles.
The prolific striker has years of Premier League experience behind him having played for Chelsea, Newcastle United and West Ham United.
The 29-year-old striker scored seven goals in 13 appearances for the Hammers four years ago to keep West Ham in top-flight football.
Recently appointed Beşiktaş manager Şenol Güneş has however, been keen on keeping hold of Ba next season.
