Players had to register with a club each season, even if they stayed with the same club as the previous season. A player was not allowed to play until he was registered for this season. Once a player was registered in one club, he could not be registered in another club or play for another club without the permission of the FA and the club that held his registration. However, players were free to join another club before the start of each season, even if their former club wanted to keep them.
