The most popular sport in the world is football but in the United States it is football. What could be the difference? Football played in Europe and other parts of the world is all about the feet and the ball however I America, football is about hands, feet and the ball. American football is somehow more like rugby the only difference rugby players never wear padded uniforms.
Football and soccer differ because of one main thing: football is played mostly with the hands and less with feet and soccer is played with the feet and only one player, the goalkeeper is allowed to use his hands in the game.
