Photos: Joel Campbell and Alexis Sanchez among those in Arsenal training

The Arsenal players trained ahead of their first European game this season.

Arsenal’s players have been put through their paces ahead of their first Champions League match of the new campaign.

The Gunners take on Dinamo Zagreb in Croatia on Wednesday evening with Arsene Wenger’s side looking to get off to the best possible start in a tough group.

As well as Dinamo, Arsenal also have to play Olympiakos and German giants Bayern Munich, meaning they really need to get three points on the board as soon as possible or risk going into a double-header against the Bundesliga champions needing to play catch-up.

Arsenal have impressed after their poor start against West Ham United, and with three clean sheets and 10 points taken from a possible 12 Wenger’s men are in fine form.

Among those players in training on Tuesday was Chilean international Alexis Sanchez who is still waiting for his first goal of the new season.

The same cannot be said for Theo Walcott, who was also caught on camera having netted in the recent 2-0 victory against Stoke City.

German international Mesut Ozil, Costa Rica star Joel Campbell and French forward Olivier Giroud were also training as they bid to start the upcoming clash.
