In Nike's thinking, to sell a kit every fan, every year (each fan is a potential customer target) is that no fan will buy the same, identical kit year after year. So ever kit has to be changed each year to a degree.
Fan's thinking is that the kit should be one way and never messed with.
So, ifyou go for the fans wishes, then Nike suffers with their sale objective and jeopardise a bigger kit deal in the future. If you go with Nike's wishes the fans suffer. Yet fans moan they are are lacking behind with the top kit deals and deserve a better one, Nike wont do that if they have their hands tied behind their backs by the fans.
some will moan that United , Liverpool, Chelsea, Madrid, Barca etc etc dont have that problem and regain their iconic kits .... but that is because they are literally decades ahead of us of global success and history. City dont have that level of history as those teams have established already over the decades. Nike/Adidas/Puma cant use that as marketing trick to guarntee sales with City. Not yet at least.
So we have to either have a kit we want and not have a super mega kit deal, or have an increasing kit deal with changeable kits. That is our current situation.
