The Premier League is reportedly exploring the possibility of allowing six substitutions per match, up from the current limit of five. According to a report by BBC Sport, the proposal was brought up during the recent European Club Association (ECA) general assembly in Rome.

Representatives from top English clubs — including Manchester City, Liverpool, Arsenal, Manchester United, and Nottingham Forest — were in attendance, highlighting the level of interest within the league to further modernize the game.

In addition to the proposed increase in substitutions, clubs are also considering expanding matchday squads from 25 to 28 players. However, any such changes would require the green light from the International Football Association Board (IFAB), the global body responsible for the laws of the game.

Background: From COVID-19 Measures to Permanent Rule Changes

The five-substitution rule was first introduced in the Premier League in May 2020, as football resumed amid the COVID-19 pandemic. It was initially intended as a temporary measure to protect player welfare in a congested calendar.

However, for the 2020/21 campaign, the Premier League controversially reverted back to the traditional three substitutions — a decision that stood in contrast to most other top European leagues. After growing pressure from managers and player welfare advocates, the league made the five-sub rule permanent starting from the 2022/23 season.

Currently, a sixth substitution is only permitted in cases involving suspected concussion, as part of global efforts to improve protocols around head injuries.

What's Next?

While the idea of a sixth substitution remains in the early stages of discussion, its potential approval would represent another significant evolution in the modern game. With growing fixture congestion, international commitments, and increasing awareness around physical strain on players, this change could receive strong backing — especially from clubs competing on multiple fronts, such as Champions League contenders.
