A Whole Week Of Betting On The Underground

In order to limit corruption and to make it easier to monitor any suspicious betting patterns on games, the German Bundesliga only announces match officials on the day of the game.
Serie A announces weekend officials on the Friday.
UEFA releases Champions League officials two days prior to the rounds of matches.

The English Premier League disguised as the PGMOL appoints referees on the Monday at 16:00 hours making detection of any global betting fraud a much harder task (I'm employed as a consultant by a betting detection agency and I can assure you that this is the case).

But surely EPL referees aren't involved in matchfixing and corruption.

Oh, hang on...
