Arsenal forward Olivier Giroud showed fans that he and the rest of the squad are in a relaxed mood ahead of their Champions League tie against Napoli by mocking teammate Mesut Ozil.

The Frenchman posted a photo of the German international wearing pyjamas in the corridor of their team hotel in Italy, with Laurent Koscielny and Mathieu Flamini also getting involved in the photo.

Giroud accompanied the picture on Twitter with the message: "We love your 'pyjamas' Mesut."

Avoiding a three-goal defeat or securing a draw will ensure that the Gunners go through to the knockout phase of the European competition.
