Rules are arbitrary so should reflect level playing field and carry on the entertainment wherever possible.

One of the rules says the referee has final say so attempts to override that as we increasingly see with technology in cricket and tennis merely serve to change the rules themselves.

To return to Michael' s point, an advantage has to be seen to be such a thing so the countdown the referee plays in his head is to see if the advantage was as advantageous as a free kick, hence my view is that the rule works fine.

There is a lot of money at stake in 2% of all football matches played under FA, FIFA etc rules. There is the matter of the vast majority of the rest of football. Technology? They can't afford a groundsman let alone a camera or two.

Where business interests clash with the rule that puts the referee in charge, it is business that needs to think on, not the rule book.

My tuppence anyroad.
