Arsenal trained at their London Colney base before flying out to France on Tuesday ahead of their Champions League group opener against Marseille.

Mesut Ozil and Olivier Giroud have been passed fit for Wednesday's game while Per Mertesacker is back in contention after missing the win at Sunderland.

Isaac Hayden and Chuba Akpom are both in Arsène Wenger's 18-man squad to face Marseille but Serge Gnabry and Emmanuel Frimpong have not travelled to France.

Our club photographers sent back these exclusive pictures.
