What are the reasons Brazil developed the players in the first place to build that legacy is probably explained by social factors that in a previous thread sabre alluded to, what you could call the underlying the difference. Being a football crazy nation but at the same time (perhaps) not having the infrastructure or organisation of a "developed" nation must mean more kids play the game in a more informal, relaxed setting (perhaps the weather is a factor) where the ball mightn't even regulation standard - if it's a ball at all
- and where the pitches undulate; under these conditions agility and control become more important in extracting enjoyment from the game itself (having a kickabout with an irregular ball must require more skill to keep the game fluid, and so to make it enjoyable); and then when it comes to moving on to playing in a more formal setting their skillset is already largely developed, and so for what they may lack in organisational awareness, they make up for in the skills they've already acquired - the basics that after a certain age become essentially "unlearnable" (though improvable) qualities (whereas organisational skills can be learned as they depend more on simple concentration and hard-work). When you compare such a setting to an English or European one; playing in a formal - you could even say rigid - setting, in organised groups with the best balls and grass pitches, where - because they play in groups, against groups - (an identifier) - winning trumps just about everything. "We're better than you" (their mums and dad's even sing songs about it ffs).
