Arsenal have made two changes to the side which defeated Crystal Palace 2-1 at the weekend for the Champions League qualifier against Besiktas in Turkey, Olivier Giroud comes in for Yaya Sanogo up front, and Nacho Monreal replaces Kieran Gibbs at left-back.

The left-back Gibbs has been ruled put for three weeks after suffering a hamstring injury in the win over Palace.

Giroud comes in for Sanogo for his first start of the season. He scored Arsenal's third goal in the 3-0 Community Shield victory over Manchester City earlier this month.

Alexis Sanchez makes his first start for the club in European competition after his £35m move from Barcelona.

Former Chelsea striker Demba Ba starts up front for Besiktas.

The Gunners have won all 12 of their previous Champions League qualifying ties.

Arsenal: Szczesny, Debuchy, Chambers, Koscielny, Monreal, Arteta, Wilshere, Ramsey, Sanchez, Cazorla, Giroud.

Besiktas: Tolga, İsmail, Motta, Ersan, Pedro, Olcay, Veli, Necip, Oğuzhan, Mustafa, Demba Ba
