Subs in injury time should be banned. If your not on by the 90th min then you miss out.
So what if you're defending a 1 goal lead in injury time and one of your defenders breaks their leg?
Hardly fair!
i don't see any need to change it :~
Injury time is quite simply a farcical concept. Why can't they let referees stop like clock like in every other sport? Blow the whistle at 90 minutes, while allowing the last attack to happen as happens now at the end of the game.
I just don't see the point.
It's all about fitting TV schedules.
Add a proper time keeper, with time remaining posted on a clock, a la NFL, NBA, NHL, and it's likely that football matches would surpass the two hour window they now conveniently fill.
At present, match officials are made well aware of the need to get the match done within a certain time frame so that a pre-sold amount of advertising can be delivered. As a result, a lot of wasted time goes unaccounted for. That would be a very hard aspect of the game to overcome.
