I'll keep this short and sweet. Is the experiment in the Champions League games of having the two additional officials on each goal line working? I don't recall seeing them having to make a crucial decision in any of the games I have seen. So no game changing decisions either way.
Has anyone seen anything by these goal-line officials that have made their presence worthwhile?
Is this something that will be successful enough that it will be put in place for all the major leagues in the world?
