Arsenal will be without number one goalkeeper Wojciech Szczesny for their Champions League opener against Montpellier.
The Gunners travel to take on the French champions tomorrow night in Group B but Szczesny will not make the trip as he has an ankle injury.
The Poland international returned in the 6-1 Premier League win over Southampton on Saturday after a two-match absence with a rib problem but is now sidelined again with Vito Mannone set to take over.
