Di Stefano is not the easiest of men, even today, and he could be a touch unpredictable. But I'll tell you what dominated his life: the enormous desire to win and to be the best at any cost. If that was threatened, he could be as stubborn and merciless as a young child. He was just as ruthless with himself, and if his own form wasn't quite there - it can happen to anyone - he would make up for it with energy and enthusiasm, and sheer effort if necessary. And he wanted the same from everyone else. He didn't like strangers and if any approached he would clam up and appear very unfriendly, but if someone he knew introduced a person to him, a friend, a supporter or anyone, he was charming and hospitable.
Di Stefano, anyway, had a right to grumble if he wanted: he was a great player and saw things others didn't see. No game is perfect, there are always mistakes, and Di Stefano would have a list of them in his head at the end: so-and-so didn't move into space quick enough; somebody should have seen him in the position he had found, but where was the pass? I never minded.
