Many a player has been on the receiving end of his infamous half time (and in game!) blasts, but it appears Sir Alex has mellowed with age and the hairdryer is no longer a necessity.
The image of Sir Alex exploding on the touchline is one that sends shivers down the spine of many a referee and player, so you can only imagine how much worse it is when behind closed doors.
But players can rest easy now, as Sir Alex insists the hair dryer has gone into retirement:
“I don’t have any confrontations really, not nowadays, although maybe when I was younger I would have.
“If a player answered me back I would head straight for them, this is where the hairdryer treatment comes in. I didn’t allow a player to beat me in an argument.
“Now I am older and more experienced and because of that and my time at the club the players have more respect.”
But this doesn’t mean Sir Alex has suddenly become a soft touch. He admits he can still have the occasional flare up but when he does, it is usually necessary:
“There is nothing wrong with losing your temper if it is for the right reasons – sometimes you are better getting it out of your system.”
