Shambles .Typical isnt it ,I thought it was supposed to eliminate the human error and take away the doubts .The problem is the officials cannot decide when it should be used !.Surely it should have been used on the Willian non penalty decision and if it was how come the viewer didnt know at the time ? .Also every time there's a query the players are clamouring to the ref for its usage .Teething problems I hear you say but people are getting paid good money to implement this and they cant even think it through properly .
