On the Nike website they have stuff I’m sure I haven’t seen in the shop.Late reply, but only just read this. Not sure how reliable kit info in December can be, but I fully expect the shield to go next season. It's a clever way of dating loads of the merch. I've been thinking this since my preseason top arrived and I clocked it had the crest in a shield on the sleeve. There didn't seem to be any reason for that to be there other than to make it clearly be from the 17/18 range of merchandise.
Like this hooded cockerel sweatshirt
