Besiktas is interested in signing Mehmet Aydin from FC Schalke. He is currently available on a free transfer as there are no signs of a contract extension with Schalke. The 23-year-old's versatility, having played 26 matches this season on the right flank and being capable of performing both as a right midfielder and a right-back, makes him an attractive prospect. Aydin, an academy product, has accumulated 71 professional appearances for Schalke. Besides Besiktas, Basaksehir, Werder Bremen, and Hamburger SV have also shown interest in acquiring the former Germany U-national team player.
