A year on from his release from Arsenal, Oguzhan Özyakup is now rated in the €20 million class by Besiktas.
The 20 year-old midfielder was outstanding in his first senior season of football and is now attracting interest from bigger clubs.
"We do not want to sell him, not even for €20 million. The coach wants his star player, we will not let him go," said board member Ahmet Kavalce.
