Of course it wasn't an accidental kit reveal!! Blimey. They don't post anything by accident, especially placing a new kit on a new signing.
When I first saw it, I was surprised, it's not a huge step away from our white second kit. Derby had a very light mint change kit a couple of seasons ago [ with black shorts too ], when you watched them on TV, it was very similar looking at that distance.
Overall though....what a lovely shirt! Like the colour, like the design in it, top class effort, three great looking kits this season for sure.
