It seems like it gets earlier and earlier each year - the weather cools, the leaves turn, and someone on the Internet posts a picture of the clothing Arsenal players will wear in the following season. This year's leaker follows in Arsenal's odd celebrity-athlete-expert history; after Boris Becker comes Linford Christie.
The retired sprinter, gold medalist for Great Britain in the 1992 Barcelona Olympics, tweeted a photo he took with Bacary Sagna, Olivier Giroud, and Thierry Henry, in which the three players were decked out in Arsenal gear. Sagna's in a fairly typical Arsenal hooded sweatshirt, but Henry and Giroud are in Puma-branded Arsenal clothes. Giroud sports a windbreaker-style training top that looks like something from the new Star Trek movies, and Henry is wearing a super-tight shirt that could be a training top, but looks more like something that could be a home shirt. It's not dissimilar to the shirt Arsenal wore in the 2004-2005 season, so there's that.
It looks fine. It's a red shirt with white sleeves. It's got an Arsenal badge on it, and a Puma logo and the Emirates Air logo on it. I don't have a lot more to say about it.
