Great genetics are not necessarily a precursor for success in the game. Brazilian Legend Pelé has often said that soccer stars are not born. Without proper soccer training a player will never reach his full potential. It is true that great speed would benefit someone who plays as a winger but would not be as useful for a goalkeeper. The greatest advantage of soccer is that it is not as discriminating as basketball or volleyball. There are no limitations when it comes to physique and it all comes down to individual soccer skills.
