PHOTOS: Arsenal in training - Wenger issues Wilshere instructions, Podolski all smiles

We compile the best photos from Arsenal's training session ahead of their match with Besiktas.

Arsenal have been pictured in training ahead of their crucial match against Besiktas tonight.

The Gunners take on the Turkish side at the Emirates this evening knowing that they must win the tie if they are to progress to the Champions League group-stages.

After a disappointing 0-0 stalemate in Instanbul last week, Arsenal are in a slightly vulnerable position, even if they go into the tie as heavy favourites.

Arsene Wenger’s side know that they will have to be wary of conceding an away goal as they press to get an advantage in the tie, otherwise their position could really be in jeopardy.

They trained yesterday in wet conditions ahead of the tie, but seemed in a focused mood.

Pictures have been taken showing Wenger offering instructions to Jack Wilshere, while Lukas Podolski appeared to be having fun during the session.

The German has been linked with a move away, but an injury to Olivier Giroud seems to mean he will be retained and he, like the rest of the squad, will be determined to avoid an upset tonight.

Here are the best pictures from Arsenal’s training session yesterday.
