Bullying,
Falling out with senior players and club staff,
Picking public fights wi refs and media,
Sticking to his ideas,
Giving out fines for petty offences,
Selling 1st team regulars for not meeting his high standards, Running clubs his way or nowt....
That guy Ferguson has been doing all these things since the 70s with East Stirling and he's done no too badly in the game:-D
