Hear something too often and it loses all impact. There was a point, about a decade ago, when Journey's Don't Stop Believin' seemed to be playing in every shop, on every radio station, interminably. After a certain point, it became little more than a mildly irritating noise.
Less is more, as the saying goes. Too much of anything is a bad thing, etc, etc. There is a wider point to be made about football generally, perhaps, but it seems particularly apt regarding one specific phenomenon.
