According to a report by Fatih Dogan in the Daily Turkish newspaper Sabah, Besiktas President Fikret Orman is open to selling the Croatia international this summer.
The report goes onto confirm interest from West Ham, Fulham and Everton. Per the source, Everton have made the most serious offer for Vida.
Sabah go onto state that Everton tabled a £16 million bid for the 29-year-old centre-back.
Besiktas are expected to revamp their squad over the summer and need to raise funds in order to do so. The Black Eagles finished up the season in fourth spot and will play in the Europa League this season.
