5 substitute rule has been given the green light by the IFAB.
This doesn't mean that the Premier League have to implement this rule, although I think they will.
I can see the reasoning for it:
- Pretty much no break between this season and next season.
- Internationals/Nations League still in place during domestic breaks next season.
- Euro 2021 follows next season immediately.
- Only a short break between Euro 2021 and 21/22 season.
- Mid-season World Cup will delay the finish 21/22 season.
- Not much break between 21/22 season and 22/23 season.
Safe to say it's going to be almost non-stop for 2-3 years.
I can see why clubs with small squads won't want it. A club like us will massively benefit from it, huge squad to make a difference and can keep top players happier.
I think they have to keep the rule of doing it over 3 substitute stoppages though or teams will time-waste and take the piss with it.
