Glasses, ref!

Interesting suggestion in a letter to my paper the other day that controversy is part of the very soul of football, and that bringing in more officials, with or without technological aids, would change the essence of the game fundamentally. Would we really want a game where every decision is spot on, and correct beyond any shadow of a doubt? What would there be to talk and argue about in the pub afterwards? Personally I don't think there is any real danger of that - even with the benefit of slow-motion replays, more often than not there is an element of uncertainty. Did he dive or didn't he? Just where was he tripped - inside the penalty area or outside? Was he level with the last defender or offside? Certainly given the standard of technology we have today, there would still be arguments. I think having more officials is a good idea though.
