The message you left me was rather offensive, it's not like I'm vandalising Wikipedia. 77.250.200.70  
The fact that it is so famous is of extremely important encyclopedic value, since most readers will have no knowledge of the fact that the Ajax Academy is any more important than the Chelsea Academy (for example). The Chelsea Academy has in fact been modeled on the Ajax academy, and has been implemented by Piet de Visser and Henk ten Cate (well until Grant was fired). The Barcelona academy was totally based on the Ajax Academy and was implemented when Cruyff was manager there. These are historical facts and it's not like I'm some kind of marketing executive from Dubai trying to say that Manchester City has the best academy ever. Incidentally, the Ajax Academy in it's current form was originally set up by Rinus Michels, who is credited with the invention of a major football tactic known as "Total Football" (as played by Ajax, Barcelona, and Arsenal today) and was named "coach of the century" by FIFA in 1999. It is not a peacock term if it has been widely recognised and acknowledged and can be referenced by multiple sources like the BBC and Fifa. 77.250.200.70
