Player's squad numbers were introduced to the Premier League for the 1993-94 season and have been in use ever since. Prior to this, players simply wore shirts numbered 1 to 11 with substitutes normally given the 12 & 14 shirts. So far, 44 different clubs have participated in the Premier League since its inception in 1992-93. I've researched and compiled tables of nearly all the participating club's player's squad numbers and they can be viewed at the top of this page... http://www.myfootballfacts.com/Premier_League_Stats.html ...there may be a few updates after the January transfer window and I'll update the tables as soon as I get a spare moment. Enjoy!
