Ok I agree that I probably got a bit carried away with myself.
However I would add two things. Firstly, Allardyce does indeed have many personality traits that are common place in sociopaths. And when I say many, I could probably come up with at least a dozen if I tried hard enough. Secondly, many sociopaths lead normal lives and most casual acquaintances will even consider them good blokes/lasses. Many are able to control the more sinister traits associated with sociopathy, which only really come to the surface when they are backed upto a wall. Allardyce is a very wealthy individual and is extremely unlikely to ever be in that position.
You seem to be putting him in the same bracket as most football managers (apologies if I got that wrong) but I disagree with that entirely. His ego is on an entirely different level.
