In the 2022/23 season, clubs are allowed to make five substitutions. This has increased from three – the permitted number for most of the Premier League's 30-year history.
The Premier League has only once before permitted five substitutions in matches. This was post-lockdown, when squads were decimated by COVID-19 and games were being played in the middle of summer.
Despite being allowed to make five substitutions in a game, however, clubs have to make them in three permitted blocks – not including half-time. This means that if a side wants to make all five changes, at least one double-substitution has to be made.
