Real Betis have rejected a €15m offer from Besiktas for playmaker Ryad Boudebouz, according to BeIn Sports in Turkey.
The 28-year-old made just 15 La Liga starts for Los Verdiblancos last campaign but is said to be rated highly by coaching staff at the club.
Istanbul-based Besiktas are said to have seen their initial bid for the Algerian international rejected but may return with a renewed bid.
Boudebouz joined Betis from Montpellier last summer in a reported €7m deal having previously played for Sochaux and Bastia.
