The 23-year old came through the Gunners' ranks but managed just two League Cup appearances before departing for the Turkish club in 2012.
He has since gone on to feature 108 times for Besiktas, scoring 13 goals in the process. Ozyakup’s versatility is one of his main strengths and he is capable in both a deeper midfield role and just behind the striker.
