13 - Unlucky For Some

English Premier League referees should be selected from a wide group of individuals.
They are not.

There are only 17 currently active PGMOL Select Group (sic) referees officiating at EPL games.
And, of these, 4 refs have only had one game apiece this season.
So 13 referees have covered 94% of EPL games whereas in the German Bundesliga, 23 referees are used in an 18 team league.

13 referees is too small a group and is far more prone to corruption.

Additionally, one individual selects every single appointment.
Just imagine what would happen if a bookmaker or an insider trader were to gain control of this one man in the most liquid betting market on the planet.

Oh, hang on...
