I was going to post before but couldn't be bothered, the people that do these tricks could use a tennis ball, or a beachball, it wouldn't matter, tricks like that have no bearing on footballing ability.
Every one of these trick master types tries ends up doing vids on youtube and never making it as a professional footballer. You see the tricks thing on soccer AM and the players are crap at football because all they think is if they do tricks they'll be amazing footballers.
Thats why English footballers seem to be getting worse, kids learning football seem to think keepy uppies has something to do with passing technique, movement, vision and in general footall, it doesn't.
The best footballers in the world spend dozens of hours a week using a football, a level of control is natural but they gain it while passing, shooting, moving and playing football. THe "trick" doing guys ONLY learn the control and nothing else, if people want to know why English youngsters in general aren't close to the best in the world, this is the reason.
The best few players in the world right now, Xavi, Fabregas, Lampard, Iniesta, Messi, Ronaldo, of them Ronaldo's the only one who uses "tricks" quite frequently as he plays but most of the reason he is good is his movement, vision passing and shooting ability, Messi just runs hard at people, the others are all about perfect simple passing. Joe Cole is one of the "trickiest" players in the premier league and he's completely forgettable, Chelsea "lost him" and haven't noticed yet, would Arsenal notice missing Cesc, would Utd miss Scholes, would Chelsea miss Lampard.
