Manchester United's new 'fourth kit' would likely fly off the shelves - if fans could actually buy it.

A slick adidas strip has been released by EA Sports' mega-game FIFA 18 , but will only be available in the virtual world to Ultimate Team players.

The bold graphics are said to come from the seats of Old Trafford, and are one of four kit releases from some of Europe's premier clubs.

Real Madrid's Football X EA Fourth Kit offering features Marcelo, Gareth Bale, Karim Benzema and Toni Kroos' likenesses in all black, with only the logo, sponsors and numbers in white.

Juventus has taken its new-age logo and run it on the entire front of the shirt, along with black shorts.

Bayern Munich's kit is one for fans of the old school, with a simple triple sash playing on adidas's three stripes.

This is the first time the adidas football design team has worked on kits purely for digital release - but are sure to see fans calling for them to be released for real.

Only FIFA 18 players who made their team one of these four clubs before December 15 will have these kits automatically added to their arsenal.

Otherwise, the kits will be available in packs as tradeable items or on the transfer market.
