Arsenal training gallery ahead of Champions League clash with Borussia Dortmund.

Arsenal's player have been pictured in training ahead of their important Champions League match with Borussia Dortmund.

A draw would be enough to see them qualify for the knockout round, while even a win would only place them two points behind the Germans with a game to go. Lose, and they could be overtaken by Anderlecht.

Teenage striker Chuba Akpom featured in the session, likely to be named on the substitute's bench. Olivier Giroud was also present, but will miss out because he was not registered in the Champions League squad, with the club not expecting him back from injury. Joel Campbell also featured and should make the 18.

Laurent Koscielny was a key returnee, with Arsene Wenger going on to confirm he is available for selection, a huge boost for the club.

Jack Wilshere, Wojciech Szczesny and Theo Walcott were all missing, with the first two picking up injuries against Manchester United at the weekend.

Santi Cazorla stood out in the session, for his questionable attire, wrapping up nearly his entire head to protect himself from the cold.
