How do you become a soccer player?
To become a soccer player professionally, you have to be very good at it. And the way to be good at it is practice. Improve your accuracy, range, height of when kicking the ball, ball control is very important and knowing your position is also very important. Most professional soccer players without even thinking anticipate where the ball is going to go. Soccer is all about thinking.
In America, none is required, but most players get drafted in college just like football, so if you want to become a pro-soccer player, finish high school, get into a college with a soccer scholarship (for playing exceptionally well), and if your lucky and very good, you might get drafted to become a pro-soccer player.
