15. Sir Alex Ferguson
‘Fergie’ led Manchester United for 26 years and is the most successful coach in British history. He won 13 Premier Leagues and two Champions Leagues in a glittering career. Evidently, Ferguson had a brilliant mind but he wasn’t perfect. Firstly, he was notoriously grouchy and refused to talk to the media on many occasions. He also threw a cleat at David Beckham’s head in anger.

Meanwhile, he earned notoriety for his hairdryer treatment. This was where he vented his fury at an individual from the privacy of his office. One of the wackiest aspects of his career was the inability to reign in his venom. He regularly targeted referees and officials. Yet this often resulted in touchline bans for his troubles.
