There's a good chance someone at Arsenal has lost their job tonight after making huge error.
On Tuesday evening, the club uploaded a video to their official YouTube channel, but viewers were quick to notice something in the video that definitely should not have been there.
The video was online for about an hour, after someone discovered that it contained a sneak preview of the yet to be unveiled Puma home kit for the 2015/16 season. You can see the full kit in the screenshot below, on the far left, being worn by a blurry Laurent Koscielny-like figure. Maybe it's Olivier Giroud... we definitely need our eyes tested.
