Come on, you can understand what i'm saying, i gave you an example, Aguero is more apealing to fans all over the world than Rossi, wich equals more shirts sales, more Marketing opportunities.
It wasn't a fluke IIRC that When diego came here, his shirt sales were ranked number one among Juve players.
@ mfdoom: tell that to RM, popularity = money = good players, plus it's not like the more poular player is the bad one, he's better both football wise and economical wise.
