I'm old enough to have been around during the Mercer v Busby days. Both absolute gentlemen, they got on well and always showed great respect for each other. Both had great success without bullying, snarling, making snide comments and generally mouthing off. Despite my total enmity towards United, I didn't particularly dislike Busby, but I always despised Ferguson. A horrible, aggressive, conniving, tyrannical, devious, degenerate toss-pot and the human personification of the contents of septic tank.
As I once heard my local Indian table waiter say to a customer "May the fleas of a thousand camels infest his armpits"
