The Spanish giant's website states: "the kit's grey colour, which is called Silver Glory, is Adidas' way of paying tribute to all the trophies Real Madrid have won over the course of the club's history, as well as all those titles still to come."
Silver is not often the colour associated with glory, particularly for Manchester United and it's dreaded grey kit, but that does not seem to have phased the 10-time European champion.
Notably absent from the photo Real Madrid released was club captain Sergio Ramos who is being targeted by Manchester United.
