There are both physical and mental aspects to how to play soccer like a pro. Physically, players must be in top shape and must consistently work on improving their skills. There will probably be a few professional soccer players that nonprofessional players look up to, and they can use those players as role models and try to emulate their style of play and approach to the game. Whether the admired player is Marta or Lionel Messi, Arjen Robben or Alex Morgan, aspiring pro players can learn from their moves and their attitudes.
There are several aspects to the mental part of the game. Learning how to play football like a pro means being determined and refusing to give up even if the team is down two goals in the final minutes of the game. Another important mental aspect of how to play soccer like a pro is teamwork. Players must be able to communicate with their teammates and must be able and willing to make difficult decisions such as passing to a teammate who is in a better position to score a goal.
A player who wants to learn how to play soccer like a pro also needs to work on cultivating their vision on the field, an ability to think several steps ahead and the capability to quickly problem solve. For example, one difference in a pro and amateur soccer player might be that the pro sees more possibilities and openings when approaching a defensive line with the ball than the amateur player does.
