A goalkeeper is a player in soccer whose primary role is to prevent the opposing team from scoring by guarding the goal. Positioned in front of the goalpost, the goalkeeper can use their hands to block shots, unlike other players who can only use their feet and body. They are crucial in organizing the defense and often act as the last line of defense against attacks. Goalkeepers wear specialized gear, including gloves and padded clothing, to protect themselves from impact. They must possess quick reflexes, good positioning, and strong communication skills to coordinate with their teammates. Famous goalkeepers include Lev Yashin and Gianluigi Buffon.
