"Let us say that you and I coached two teams with kids that are 10, 11, and 12 years old and all about equally good. You try to teach them to play good soccer, a passing game with tactical basics while I tell mine to only play long balls and try to shoot. I can assure you that at first I will always win against you, by using your mistakes. Intercept a bad pass and goal. If we, however, continue with the same training methods during a three year period, your team will have learned how to play while mine hasn't. That's how easy it is."
