Can we make a unofficial rule that we will not mention

Shirley, it is the official's responsibility to make sure Sanchez is the correct distance away from the touch line. If they a happy with Sanchez's position when the throw is taking place then, in that instance, the thrower is guilty of ungentlemanly conduct and should be carded. What Sanchez did was embarrassing and its only achievement was getting the other guy off getting a 2nd yellow card

All these laws that involve people being x yards or y metres away are utterly ludicrous, of course, in a sport that doesn't have the means for measuring such things properly. Everything ends up being guessed at by the ref, which inevitably leads to dispute.

Mind you, I've always found the laws of football ridiculous, since so many of them are either widely ignored, impossible to enforce consistently or simply questions of interpretation.

It is in many ways, a very silly game.
