Besiktas has reached an agreement with Atlético Madrid for the signing of Ghanaian prodigy Bernard Mensah in January.
The Turkish club has convinced the Rojiblancos to take all rights of the player.
The leaders of the Turkish league, Besiktas are negotiating with Kayserispor, where Mensah is playing on loan from the start of the season to release the player in the summer.
Mensah has emerged on the radar of Black and White lads following his sterling performance in Turkey for the past two seasons.
He had a successful loan spell with Kasimpasa last season where he bagged many goals with seven assists in 32 outings.
