Squad numbers became optional in the three divisions of The Football League at the same time, but only 10 out of 70 clubs used them. One of those clubs, Brighton & Hove Albion, issued 25 players with squad numbers but reverted to traditional 1–11 numbering halfway through the season.[11] In the Premier League, Arsenal temporarily reverted to the old system halfway through that same season, but reverted to the new numbering system for the following campaign.
