The reason I'm posting this,is because there's something... interesting in that pic.
Plus,someone posted this on the comments of a website:
"Also, Man United have a well-established tradition of carrying over a kit from one year to serve as the third kit for the next, so expect the current white away strip to be the pick for that. Besides, the team needs colour variance for both domestic and European competitions.
Next, the away kit for 2013-14 will definately be black, with a rumoured (*ahem*) “touch of blue”. Although United only starting using black in kit design in 1992, courtesy of Umbro, Nike will make good on the in-house custom of introducing a black away kit every three years. However, don’t expect the same collar on the 2013-14 away kit. Nike has a new neck design in store for that.
Lastly, don’t ever count on seeing a green-and-gold kit anytime soon, if ever. Turns out many in the organization can’t stand the colour scheme. So much for history."
So,the gingham shirt is apparently fake (it's navy blue)
