O/T:- Added on time

[sidders]

One of the good things that emerged from the World Cup was a more realistic attitude by referees towards added-on time for stoppages through injury, refreshment, subs, etc but I fear that now we are 'back to normal' added-on time in most English games is ridiculously understated.
I've actually used my stopwatch on a number of televised games as a guide to what value the referee should be according games and in most cases it's woefully short.
What this means is that it pays teams to waste time if they are in a winning position or even drawing against the odds. It pays to make last minute substitutions or delay throw-ins and free kicks by precious seconds.
I have often thought that football should learn from a number of other sports that give the job of time-keeping to other than match officials.
