I can't tell if the trim is black or navy, it looks black on the left sleeve and navy on the right. I'd expect it to be navy.
Someone has replied on that thread showing the navy/purple kit as the new away kit and the turquoise one for the new third, but they have replied saying it's not. The navy & purple is really nice so I'm hoping it's legit!
The away kit is a concept but it's confirmed to be those colours.
Third kit will be turquoise.
