Holland and France have the two best youth systems in the world IMO. But Brazil is unmatched in numbers. I shudder to think what they'd be like if they had the right infrastructure and coaching at a young age. Sure you can't coach some of it but if you look at England, Italy, Germany etc. players like Ballack, Gascoigne and Totti are massive exceptions. Whereas Holland and France continue to produce bucketloads of players with flair and creativity. Similarly to Brazil, but if they recieved the same coaching as in Holland and France I have a feeling they'd be even better.
Things are changing throughout the world though as other countries try to copy France and particularly Holland's sysetms. That's why the current English team has more "flair" than they've possible witnessed in their entire history. With guys like Gerrard, Lampard, Cole and Rooney.
Also that's why the English league is played at a fast pace with a focus on phyiscal strength, speed and athleticism. The Italian game is a far more technical, defensive game. Holland invented the concept of Total Football and still look to play that sort of game. Brazil is full of creative play and showboating too where you can get guys who aren't physically great by any means but can be a star player. Whereas in England you get players like Agbonlahor, good player, who are in the team because of their speed (although I admit he'll probably develop into soemthing alot better). Things are changing though obviously and Australia's changing too. Typically we used the English model of coaching and youth development and stuff and the focus was on a physical team with the result was Kewell being a massive exception. Our players didn't have the touch, movement, dribbling ability or cerativity to rival the top teams because of the system but we always matched teams physically. We're obviously moving towards a Dutch and French style with Brazilian elements in it too. The difference it made is visible simply from the World Cup with Guus in charge. I still feel we have too many "old style" coaches, most of them being from the UK (not an exaggeration at all), in our game and that's detrimental IMO.
Of course that's all contentious but it's definitely how I think football is the way it is today in certain countries.
