Besiktas are reportedly willing to offer Inler a substantial contract to persuade him to leave his current club Napoli.
The 31-year-old is the target of the Turkish sports club and could leave the Partenopei before the end of the summer.
According to Tuttomercatoweb, Besiktas are readying an offer of €2.5m yearly plus bonuses for the player, which could raise his salary to €3m.
The Turks are believed to be offering Napoli a comparatively more modest offer of €3.5m for the player himself.
Premier League club Leicester City are reportedly also interested in Inler and are awaiting developments.
