He writes: "The shirt-tugging, wrestling, holding, blocking and general free-for-all at corners and set pieces is a problem fo referees - but it is not a problem for players.
"They accept it as part of the game and practise it every day in training."
He continues: "For referees, the difficulty is that there are at least three or four offences at every corner. Both sides are at it, so who do you penalise?"
Poll is refreshingly candid in his conclusion. "The easiest thing for me to do, now that I am retired, would be to deliver a stern sermon to my former colleagues.
"Yet the truth is that I didn't solve the problem when I was refereeing."
