Jahanbakhsh is going to leave Feyenoord due to lack of playing time in the team.
Jahanbakhsh, whose contract will expire in 2024, has also been linked with a move to Greek teams, his agent said.
The 29-year-old player joined the Eredivisie outfit on a three-year contract from Brighton & Hove Albion in July 2021 but just scored four goals in 37 matches for the team.
Besiktas, headed by Senol Gunes, has reportedly shown an interest in signing him.
