January 2000 was when Roy Keane raged at referee Andy D’Urso, with Jaap Stam and Ryan Giggs in tow, for awarding the first league penalty against Manchester United at Old Trafford in six years.
Back then, the FA tried to do something by consulting the captains of the clubs, one idea being that only they should speak to the officials.
That went on to be trialled. Clearly it never entered the laws of football. More and more, it feels like respect for referees has gone out of the window in the English game.
