Former Premier League referee Mark Clattenburg has revealed an altercation with Jose Mourinho that left the Portuguese boss stunned white.
Clattenburg, who spent 13 years officiating in the top flight, took charge of countless matches during Mourinho's time in England and had a front row seat for his fall from grace in the eyes of the football public.
Once heralded as the 'Special One', able to bend the media and opponents alike to his will with his quick wit and charm, Mourinho's spells at Manchester United and Tottenham after his stunning success at Chelsea were largely marked by controversy.
