Obviously its lame its not used, work a challenge system like in the NFL
jeez, there are enough stopages as it is with everyone diving all over the place, every match would go on for 6 hours like the NFL!
2 challanges each, a 3rd if you get first 2 right, cant see it taking that much time up.
They still dont agree on decisions on match of the day when they've looked at the incident 30 times so i can see that causing so much drama , esp for the managers, if you see them having a scream up now imagine what it'll be like for the refs if they take the time out to review a decision and still get it wrong.
