I think football should learn a lesson from hockey when it comes to managing time. Hockey matches are so business-like; there is hardly any time-wasting. Everybody simply gets on with their job (this is probably because the clock is not controlled by the referee, but by timekeepers). I also found it refreshingly quaint that when a substitute has to enter the field, he carries aloft the jersey number of the player he is about to replace. Yet, for all this, football continues to be miles ahead in terms of popularity.
