I thiiiiiink it's real.
Two reasons: if you zoom in you can see a repeating tonal LFC 'watermark' on the bottom half, which is something those designers like, and whatshisface on Twitter who wouldn't release a description because it was 'too soon' has endorsed it. And he's actually always right.
I think it's real, but I don't think it's the end of the world. The away kits are supposed to be lovely and it could have been worse. Not a great picture either. And it won't be launched with the slogan #BloodFireAndBigWomenBoobs or something, so it's going to be a more pleasant experience all round.
