Football originated in England in 1848 and has since spread globally. It involves two teams of 11 players using only their feet, legs and head to pass and shoot a ball into the opposing team's goal. The game is regulated by FIFA and major tournaments include the FIFA World Cup and UEFA Champions League. Key elements of football include passing, dribbling, shooting, and trapping the ball while following rules overseen by a referee. Players can receive yellow or red cards for fouls and violations.
