A goalkeeper is one of the most important players in the soccer team.
His job is to prevent the other team from scoring. Whether the goalkeeper punches the ball, catches it, or kicks it, as long as the ball does not go past the line, no point is scored.
The goalkeeper is also the leader of the team's defence. He is able to see the entire field and can instruct his teammates. The keeper can organize his team and have them pull up or stay back if needed. He can control the tempo of the game (hold the ball longer, get rid of it quicker, etc.).
The goalkeeper should have really good eye-hand coordination, not be afraid of the ball, and be willing to basically "sacrifice" his body for his team by diving in front of attackers who will purposefully knock into the keeper to score.
