Besiktas are reportedly in negotiations to sign former Arsenal midfielder Santi Cazorla who is available on a free transfer this summer.
The 35-year-old has bounced back from a career threatening injury in the last two years, by starring for Villarreal following his departure from the Emirates Stadium.
But with his contract up at the Spanish top flight side, he is in discussions over a move to Turkey according to AS, who cite Turkish reports.
Cazorla's future remains uncertain after agreeing a one-year extension at Villarreal at the start of the season having battled back from his ankle problems that ruined the latter part of his excellent spell at Arsenal.
