I think it should be given a go nut i dont think it can work , i dont think it would slow the game down , will a video ref really take that long to view the replay , will Gary neville have even finished giving out to the ref by the time the verdict comes back .
Any game you watch on tv sky have shown the replay 5 or 6 times and then it goes back to the game and the players are still moaning .
But i cant see it working there is just not enough cameras out there to monitor every game if you think about it you will need a camera on the goal line ( 2 ) following the ball so thats a min of 3 per pitch . Thats ok in the prem league when sky have cameras at every ground but what if the camera does nt have a good angle or misses the incident , What happens if the ref calls for the vid ref then he comes back and says i dont know !!! there is no way it would work in say the Irish league where most first div games have no camera's at the game at all .
What if players start looking for it for everything you could claim and offside is just as important as a goal mouth scramble , what if he is onside and the ref gives it offside then the vid over rules him does the attacker get the free kick ? its hardly the same to have a one one reduced to a free kick .
I just think it would lead to more problems than it would solve , No harm looking into it though .
