Mohamed Elneny has completed his move to Besiktas.
The Arsenal midfielder moves to the Turkish side on a season-long loan deal after falling out of favour under Unai Emery.
Elneny has found game time hard to come by under Arsenal boss Unai Emery, playing just 17 games in all competitions during the 2018/19 season. The Egypt international has found it even harder to break into the side this campaign, having not been named in any of the Premier League squads so far.
Signed in January 2016, the Egypt international made 89 appearances for the Gunners.
Elneny looked to have fallen down the pecking orders under Unai Emery after the signing of Dani Ceballos and the emergence of young talents such as Joe Willock.
Elneny is the second Arsenal star to head for the exit door this weekend.
Nacho Monreal has also completed a move away from the Emirates Stadium after agreeing a two-year deal to join Real Sociedad.
The full-back made 250 appearances for the Gunners in a six-and-a-half year spell in north London.
