While I was looking for the BBC article I came across this which sums it up really
What you will see is lots of adults standing on the touchline of a small football pitch shouting at their eight-year-old children. One of the adults may be dressed in a tracksuit, with initials embroidered on his chest. He will be shouting the loudest, most often the instruction "get stuck in" occasionally varied with "just clear it".

Have fun: Trevor Brooking wants under-eights to enjoy the game
At some point there may be a confrontation between several of the parents, following a disputed goal. If, for instance, you are watching a game in Devon things might conclude, as they recently did, with one of the watching fathers becoming so irate that he marched off, only to return at the wheel of his 4?x?4 - which he proceeded to park in the middle of the pitch, refusing to move until the referee changed his decision. What you are unlikely to see is any of the small children concerned having much in the way of fun.
