Former Premier League referee David Coote said he felt "ashamed" of the behaviour that led to his sacking in December for being found to be in breach of his employment contract.
In an interview with Sky Sports, the 42-year-old admitted to being embarrassed by footage that was published last year of him using derogatory language about former Liverpool manager Jurgen Klopp, as well as a second video which appeared to show him snorting a white substance.
