My thoughts exactly, but someone must be buying it.
Are we the only elite European team to produce our own merchandise?
If it was such a great idea, why's everyone not doing it?
Pretty much anyone with Nike don't have control of their own shops or online store, this is totally run by Nike. I'm fairly certain Adidas have gone down this model now too, although don't think they did so back when they started sponsoring us after Reebok (could be wrong but sure we still ran our own stores), however thing they produced and took a cut of all the leisure type wear which will of carried the adidas brand.
As to why isn't everyone doing it, mix of a few things really that I can think of. Some clubs simply wouldn't have the demand around the world for that type of product to make it worth while opening up distribution (own shops, localised online stores, etc) and some, I imagine, would just prefer to have the money up front and not have to deal with the issue of doing it themselves.
This massive range of non-kit/training gear is a relatively new idea, so it could well be a case of us being the first to attempt this type of method - which if it works will no doubt see lots playing catch up to try and follow in our footsteps.
