1. Teams cannot get all they want. Mandzukic foul and yellow was not a game changing call.
2. The objective is not to eliminate human error but to reduce it. i can't see why they shouldn't do it.
3. Given that there are more than 10 cameras in each game I'm confident they can do it pretty quickly
1 & 2 : your view is too naive and here I'm already disproving that view plus proving my view; I don't agree that such incidents are not game changing, a foul for sergi roberto and a yellow card for him instead for mandzukic and juve could be a game changer, we could've scored from that hypothetical free kick, sergi could be red carded later in the game...
How can that not be a potential game changer?
There are other kind of incidents, like what inter bitched on our last match, people will demand video analysis for that...
All we need to have is some people forming public view on social media to push the agenda.
You let that snowball slide and that agenda will happen, only a matter of time.
And the human factor will get even more exposed with video, in fact the video analysis itself would be the key for people to bitch about everything.
There are alternatives for certain kind of incidents like offside, we can have alternative that doesn't involve video analysis, something like goal line tech.
