Former Arsenal teammate Mesut Ozil who himself had been linked with a move to Turkey dropped a comment on the Instagram post wishing Elneny ‘good luck’.
Elneny was not registered in time for the Black Eagles 1-1 draw against Rizespor over the weekend but did watch the game from the stands at the Vodafone Park stadium.
The 28-year-old is expected to make his debut for the Black-Whites away to Gazisehir on Sunday 15 September after the international break.
Besiktas head into the break in 8th place on four points after three games – having won, lost and drawn so far this term.
