Some of the Gunners' players pulled a prank on their fans, who were asked to strike a pose with the team's new gear.

After their Community Shield victory against Chelsea this Sunday, Arsenal's players seem to be all smiles. In fact, some of them pulled a prank on their supporters, who were posing with the team's new jersey during an event sponsored by the team's supplier.

Goalkeeper Petr Cech, Mathieu Debuchy, Laurent Koscielny and Olivier Giroud, among others, were in charge of photo-bombing their supporters pics, with some not noticing the presence of the players until they had no choice to do so.
