Besiktas are reportedly close to signing Arsenal midfielder Oguzhan Ozyakup.
The 19-year-old midfielder joined the London club in 2008 from AZ Alkmaar.
Gunners coaches had high hopes for Ozyakup, however the player has only featured twice for the club's first team - in the Carling Cup wins over Shrewsbury and Bolton Wanderers last season - and he is likely to depart the Emirates Stadium for a fee in the region of £560,000, according to the Daily Mail.
Ozyakup was also an unused substitute as Arsenal lost 8-2 to Manchester United and beat AC Milan 3-0 last term.
