I don't know hos this works, that's why I'm asking. I get what you are saying and let's say Juve will pay Armani for their business-y line. Would those clothes have only the :jj: logo, or will Armani put their logo too. If not, how will people know it's an Armani-quality piece? just look at the clothing line from the Juve world tribe, no logo, no nothing; who's making that, what quality is that?
When you make quality stuff, you want to have brand awareness, you need people to associate quality products to your name. IMO we need people outside football and sports to but the :jj: branded stuff, and you can only do that if it's quality and people will know it's quality if they know who is making that.
