Soccer is played by millions of people all over the world, but there have only been few players who were truly great. How did these players get that way—was it through training and practice, or are great players "born, not made"? First, these players came from places that have had famous stars in the past—players that a young boy can look up to and try to imitate. (32) In the history of soccer, only six countries have ever won the World Cup—three from South America and three from western Europe. There has never been a great national team—or a really great player—from North America or from Asia. Second, (33) these players have all had years of practice in the game. Alfredo Di Stefano was the son of a soccer player, as was Pele.  Most players begin playing the game at the age of three or four.
     (34) Finally, many great players come from the same kind of neighborhood—a poor, crowded area where a boy’s dream is not to be a doctor or lawyer, but to become a rich, famous athlete or entertainer. For example, Liverpool had one of the best English soccer teams in recent years.
     All great players have a lot in common, but that doesn’t explain why they are great. (35) Hundreds of boys played in those Brazilian streets, but only one became Pele. The greatest players are born with some unique quality that sets them apart from all the others.
