“The laws of football now stretch to precisely 140 pages, but our comprehension of them could probably be covered in 140 characters. Football has always been a simple, intuitively understood game, with exceptions to that few and far between. Two spring to mind. The first is the offside law, the bane of pepper pots up and down the land. Though the ever-changing interpretation of offside has caused much confusion, it’s actually a pretty straightforward concept and one that is, at least, exactly defined. The same is not true when it comes to volleys. Depending which watercooler you lurk by, you will find an entirely different comprehension of what constitutes a volley.” (Guardian)
