Nike also make some of the best kits about. Puma's kits usually go to poorer sides and thus have 90 sponsors on them. There Arsenal kit looks nice though.
Actually, it's about money, Nike have more of it and get the bigger exposure from bigger teams, it actually has nothing to do with quality of kit you fooking idiot
I know. Its basically what I said lol. Nike sponsor the biggest clubs along with Adidas. the erst fight it out with the smaller clubs. Puma kits that I have seen recently are plastered with sponsors. Usually means the team or league are bums.
