Arsène Wenger has made two changes to his squad for Tuesday's Champions League opener in France.
Abou Diaby missed Saturday's win over Southampton but is fit to face Montpellier. He replaces Andrey Arshavin in the 18-man party.
Wojciech Szczesny has been ruled out with an ankle injury so James Shea has been drafted into the squad.
Damian Martinez has not been called up because he was not named on Arsenal's A list squad for the Champions League and was ineligibie for the B list.
