4. The Player's Equipment - Just like with the soccer ball, soccer equipment maintained most of the original rules in the Laws of the Game, but the way people interpret them today is quite different from how they did back in 1863. Basically the rules of soccer say that a player must wear a shirt or jersey, footwear, shin pads, shorts and socks and the two teams must have different equipment so that they can be differentiated on the pitch.
Back then however, a soccer jersey was a largely uncomfortable one and it was very simple, without too many details strapped on it. Today's jerseys are very light and comfortable and on many occasions they have the club's sponsors imprinted on them, they have the number of the player (and the name in some cases) on the back and the club's badge on the chest. These are not enforced by the soccer rules, but they have become common standards in today's game.
