Arsenal players took to the pitch for their last home training session ahead of their Champions League match against Barcelona.

With Laurent Koscielny returning to the squad, and Nacho Monreal and Hector Bellerin expected to come back in, we should see a sturdier backline than we have witnessed in the FA Cup recently.

That being said, the loss of Petr Cech, Aaron Ramsey, and Santi Cazorla, will still be felt when Arsenal take to the pitch.

Here’s the team running through their paces at Colney before heading to Spain:
