I don't know about any "professional schools of soccer" but the Major League Soccer teams have training academies:
How can I find a professional school of soccer to enter in? My dream for 2007 is to be able to attend a school of soccer for a professional career in soccer. How can I have details information on that anywhere in the world I am ready for this dream. If someone out there know good people in the soccer world please let me know. I am 16 years old and soccer is like everything for me. Really motivated and serious and responsible 16 years old boy. Thanks all and have a blessing and Happy new year in 2007. Please pray for my dream too.
